200903074 九、發明說明 【發明所屬之技術領域】 本發明係關於輸入裝置、光電裝置及電子機器。 【先前技術】 近年來，伴隨著個人數位助理（PDA )、掌上型電腦 等小型資訊電子機器的普及，於液晶面板上作爲輸入裝置 而搭載觸控面板的液晶裝置逐漸被廣爲使用（例如參照專 利文獻1 )。 [專利文獻1]日本專利特開2003 - 4345 0號公報 【發明內容】 [發明所欲解決之課題] 然而，把具備觸控面板之液晶裝置作爲電子機器之顯 示部使用的場合，有必要使觸控面板露出於筐體的表面， 所以通常以筐體按壓支撐觸控面板的框緣部分。在這樣的 構造，筐體與觸控面板的操作面之間被形成階差（參照圖 20 )，無法採用與筐體成爲一體之設計所以設計上的自由 度很低。 本發明，有鑑於前述從前技術之問題，目的在於提供 可以提高具備輸入手段的電子機器之新式樣性，更佳者爲 也可以提高可信賴性之輸入裝置及光電裝置。 [供解決課題之手段] -4- 200903074 本發明之輸入裝置，爲了解決前述課題，其特徵爲具 有：輸入面板、被設置收容前述輸入面板的收容部之蓋構 件、及跨被配設於前述收容部之前述輸入面板之一主面與 前述蓋構件之一主面而被黏接的可撓性（薄膜）構件。 根據此構成’因爲在把輸入面板收容於覆蓋構件的收 容部的狀態下跨輸入面板與覆蓋構件而黏接可撓性構件， 所以可以解消成爲損害從前的設計性的原因之輸入面板與 覆蓋構件之邊界的階差。藉此，可以實現新式樣性優異的 輸入裝置。 此外，因爲在輸入面板的主面側被配設可撓性構件， 所以輸入面板具有玻璃基板的場合，即使玻璃破損也可以 防止破片飛散。 此外，伴隨著階差的解消，可以消除在階差部分累積 塵埃，或者水滴由輸入面板與覆蓋構件之邊界浸入等情 形，可以實現可信賴性優異的輸入裝置。 亦可以是挾著前述可撓性構件與前述輸入面板之相反 側，被黏接第2可撓性構件的構成。 根據這樣的構成，因爲藉由第2可撓性構件而使輸入 面板之面板厚度方向之移動受到限制，所以可以防止對輸 入面板進行輸入操作時以輸入器具或手指之按壓力而使輸 入面板被按壓陷入深側。 前述可撓性構件最好爲薄膜構件。可撓性構件採用薄 的薄膜構件的話，可以防止對輸入面板之操作壓力變大， 此外透過輸入面板而進行液晶面板等的顯示的場合可得高 -5- 200903074 透過率，可得高畫質之顯示。此外，針對第2可擦性構件 也可採用薄膜構件，可以防止輸入裝置全體變厚’成爲可 以構成薄型之電子機器之輸入裝置。 亦可採用在前述薄膜構件之前述輸入面板側之面被形 成遮光膜之構成。 如此般在薄膜構件形成遮光膜，所以可容易形成不要 的部位之遮蔽。此外，遮光膜的位置對準也可以容易進 行。進而，可以提高設計性。 前述薄膜構件與前述輸入面板最好被光學黏接。 如此構成的話，在透過輸入面板進行顯示時’可以防 止在位於輸入面板與薄膜構件之間的空氣層的界面產生不 要的反射，而可以防止顯示品質降低而得明亮的顯示。 亦可採用前述薄膜構件於前述輸入面板之平面區域內 具有開口部之構成。如此般在薄膜構件設置開口部’可以 使輸入面板之操作面露出’可減低操作壓力而輕鬆進行輸 入操作。在本發明，因爲在輸入面板及覆蓋構件黏接薄的 構件，所以不會在薄膜構件之開口部形成大的階差，可以 幾乎無損於新式樣性而提高操作性。 亦可採在前述輸入面板與前述收容部之內壁面之間配 設黏接劑之構成。 採用這樣的構成的話，覆蓋構件與輸入面板被黏接， 所以可更安定地支撐輸入面板，可更爲確實地防止輸入操 作時輸入面板被按壓沈陷。 被黏接於前述輸入面板之前述一主面側的前述可撓性 -6 - 200903074 構件亦可爲偏光板。 採用如此之構成的話，可以成爲使被配設在輸入面板 的背面側之液晶面板等顯示手段之一部份之光學元件配置 於輸入裝置的前面側的構成。 於前述輸入面板之前面側，不限於偏光板，亦可配置 其他光學元件。例如，配置層積偏光板與相位差板之光學 元件亦可，亦可配置防反射膜或光擴散膜。 最好是前述收容部爲貫通前述覆蓋構件而被形成的開 口部。 根據這樣的構成，爲了形成收容部而進行的加工變得 容易，可以低成本製造輸入裝置。在本發明，因爲藉由跨 覆蓋構件之主面與輸入面板之主面而黏接的可撓性構件來 支撐配置於收容部的輸入面板，所以收容部自身沒有必要 具備保持輸入面板的功能。此外，輸入面板的尺寸（特別 是厚度上）的不均之影響也可以排除。 其次，本發明之光電裝置，其特徵爲具備：具有：輸 入面板、被設置收容前述輸入面板的收容部之蓋構件、及 跨被配設於前述收容部之前述輸入面板之一主面與前述蓋 構件之一主面而被黏接的可撓性構件的輸入裝置，及被配 設在與前述輸入裝置之前述可撓性構件相反之側的光電面 板。 根據此構成，藉由相關於本發明之輸入裝置可得優異 之新式樣性，可提供能夠進行輸入操作與透過輸入面板之 影像顯示的光電裝置。 -7- 200903074 作爲前述光電面板，可以使用液晶面板或有機EL面 板、電泳顯示面板等種種顯示裝置。或者是也可以使用電 漿顯示裝置或場發射顯示裝置（電場放出顯示裝置：Field Emission Display · FED) 〇 構成前述光電面板的基板，及與前述可撓性構件相反 側的前述輸入裝置之面最好被光學黏接。 根據此構成，可以防止由光電面板射出的顯示光，以 構成輸入裝置之輸入面板之基板面等反射，而可得明亮的 顯示。 前述光電面板被固定於前述蓋構件，使成爲把前述輸 入面板挾持於與前述可撓性構件之間的構成亦可。 這樣藉由光電面板與可撓性構件挾持輸入面板，限制 住輸入面板的面板厚度方向的移動，所以對輸入面板之輸 入操作時可以防止輸入面板被按壓陷入光電面板側。 前述可撓性構件可以爲偏光板。根據這樣的構成，因 爲被配設於光電面板與輸入裝置之間的偏光板被配設於輸 入面板的外側，所以可節省輸入面板的背面側的空間，成 爲在小型的電子機器也可以容易搭載的光電裝置。 構成前述光電面板的基板，及與前述可撓性構件相反 側的前述輸入裝置之面之間配置透光性的彈性構件亦可。 本發明之輸入裝置，作爲爲了解決前述課題之其他態 樣’其特徵爲具有：輸入面板、被設置收容前述輸入面板 的收容部之蓋構件、及跨被收容於前述收容部之前述輸入 面板之一主面與前述蓋構件之一主面而被黏接，同時沿著 -8- 200903074 被形成於前述輸入面板的前述主面與前述覆蓋構件之前述 主面之邊界部之階差而密接於前述輸入面板及前述蓋構件 之膜構件。 根據此構成，依循被形成於前述輸入面板的主面與前 述覆蓋構件的主面之邊界之階差的方式使前述薄膜構件變 形而密接’所以薄膜構件的表面緩和了階差而成爲平滑連 續的形狀’可以防止起因於階差之設計性的降低。藉此， 可以實現新式樣性優異的輸入裝置。 此外’因爲在輸入面板的主面側被配設薄膜構件，所 以輸入面板具有玻璃基板的場合，即使玻璃破損也可以防 止破片飛散。 此外’覆蓋住邊界部的階差而被黏接薄膜構件，所以 消除在階差部分累積塵埃’或者水滴由輸入面板與覆蓋構 件之邊界浸入等情形，可以實現可信賴性優異的輸入裝 置。 於前述覆蓋構件的前述主面與相反側之背面，被黏接 與前述薄膜構件一起挾持前述輸入面板之背面側薄膜構件 的構成亦可。 根據這樣的構成，因爲藉由背面側薄膜構件而使輸入 面板之面板厚度方向之移動受到限制，所以可以防止對輸 入面板進行輸入操作時以輸入器具或手指之按壓力而使輸 入面板被按壓陷入深側。 亦可採用前述薄膜構件於前述輸入面板之前述主面的 平面區域內具有開口部之構成。 ~ 9 - 200903074 如此般在薄膜構件設置開口部，可以使輸入面板之操 作面露出，可減低操作壓力而輕鬆進行輸入操作。在本發 明，因爲在輸入面板及覆蓋構件黏接薄膜構件，所以不會 在薄膜構件之開口部形成大的階差，可以幾乎無損於新式 樣性而提高操作性。 前述膜構件，亦可具有層積第1樹脂層、及比前述第 1樹脂層硬度更低的樹脂材料所構成的第2樹脂層的構 造。採用這樣的構成，因爲具備具有高柔軟性的第2樹脂 層，所以於輸入面板與覆蓋構件之邊界部可以使薄膜構件 柔軟地變形，對輸入面板及覆蓋構件可使薄膜構件良好地 密接。 前述第2樹脂層構件亦可於前述輸入面板之平面區域 內具有開口部。使成爲這樣的構成，因在輸入面板上配置 更硬的第1樹脂層，所以成爲可良好地防止由於輸入操作 而導致磨耗或傷痕的構成。 於前述覆蓋構件之前述收容部，最好是被形成與前述 輸入面板抵接而支撐前述輸入面板的面板支撐部。如此構 成的話’藉由面板支撐部可以限制輸入面板之面板厚度方 向的移動，所以對覆蓋構件之輸入面板的位置對準變得容 易，此外薄膜構件的黏接也變得容易進行。 前述面板支撐部，最好被形成爲由前述收容部之內壁 往前述收容部內突出的框狀。亦即，面板支撐部最好被構 成爲可按壓輸入面板的周緣部。根據這樣的構成，可以藉 由面板支撐部構成輸入面板的周邊分型。此外，藉由另行 -10- 200903074 設置與收容部不同的面板支撐部，可以降低覆蓋構件與輸 入面板之邊界部的階差的高度。 亦可採在前述輸入面板與前述覆蓋構件之間配設黏接 劑之構成。如此構成的話，藉由覆蓋構件可更安定地支撐 輸入面板，可以提高製造步驟之操作的容易度，以及輸入 操作時之可信賴性等。 其次，本發明之輸入裝置之製造方法，係具備輸入面 板與支撐前述輸入面板之蓋構件的輸入裝置之製造方法， 其特徵爲具有：在被形成於前述蓋構件的凹部或開口部所 構成的收容部配置前述輸入面板之面板配置步驟，及跨前 述輸入面板之輸入操作面與前述輸入操作面側的前述蓋構 件之主面配置膜構件之膜配置步驟，及加熱前述膜構件使 其軟化，使黏接於前述輸入面板與前述蓋構件之黏接步 驟。 根據這樣的製造方法，可以極爲容易地把薄膜構件黏 接於輸入面板及覆蓋構件，此外也可以簡便地使薄膜構件 變形而成爲依照前述邊界部的形狀。 於前述黏接步驟，最好藉由真空熱溶接法黏接前述薄 膜構件。根據此製造方法，可以極容易且效率極佳地進行 薄膜構件的黏接以及密接。 亦可具有在前述主面與相反側之前述覆蓋構件的背 面，黏接由前述背面側支撐之背面側薄膜構件的步驟。採 用如此般之製造方法，可以在黏接薄膜構件以前對覆蓋構 件固定輸入面板，可以正確地進行薄膜構件的黏接，而成 -11 - 200903074 爲對生產率提高有所貢獻之製造方法。 前述膜構件，可以具有層積第1樹脂層、 1樹脂層硬度更低的樹脂材料所構成的第2 造，於前述薄膜配置步驟，可以在前述輸入面 蓋構件之邊界部配置前述第2樹脂層。。根 法，因配置柔軟性更高的第2樹脂層，所以依 形狀而使薄膜構件變形也變得容易。 其次，本發明之輸入裝置，其特徵爲具備 入面板、被設置收容前述輸入面板的收容部之 跨被收容於前述收容部之前述輸入面板之一主 構件之一主面而被黏接，同時沿著被形成於前 的前述主面與前述覆蓋構件之前述主面之邊界 密接於前述輸入面板及前述覆蓋構件之薄膜構 置，及被配設於前述輸入裝置之與前述薄膜構 光電面板。 根據此構成，藉由相關於本發明之輸入裝 之新式樣性，且可提供能夠進行輸入操作與透 之影像顯示的光電裝置。 作爲前述光電面板，可以使用液晶面板或 板、電泳顯示面板等種種顯示裝置。或者是也 漿顯示裝置或場發射顯示裝置（電場放出顯示 Emission Display ： FED)。 本發明之電子機器，其特徵爲具備前述之

下參照之各圖面，爲了容易辨識而適當地改變了各構成要 素之膜厚或尺寸之比例。 [第1實施形態] 圖1 ( a )係相關於本發明的第1實施型態之第1構成 例之輸入裝置4 0 A之槪略剖面圖。圖1 ( b )同樣係相關 於第2構成例之輸入裝置40B的槪略剖面圖。圖2爲圖1 所示之輸入裝置40A之槪略平面圖。圖3係顯示觸控面板 4的構造之分解立體圖。 [第1構成例] 如圖1及圖2所示，本實施型態之輸入裝置40A，具 備平面俯視約略板狀之覆蓋構件4 5，被配置於由被形成在 覆蓋構件4 5的矩形狀的開口部所構成的收容部4 5 a內的 類比型電阻膜方式之觸控面板（輸入面板）4，及跨覆蓋 構件45的主面45s (圖2之前面側）與觸控面板4的主面 4 s而被黏接的薄膜構件（可撓性構件）3 0。於薄膜構件 3 0之覆蓋構件4 5側，被形成例如藉由印刷而形成的遮光 膜46’遮光膜46於對應觸控面板4的輸入部40a之平面 區域內具有矩形狀之開口部46a。亦即，觸控面板4之輸 -13- 200903074 入部40a以外的平面區域（比輸入部40a更爲外側起直到 基板本體lib的端部爲止的平面區域）係藉由遮光膜46 而遮光。 觸控面板4的厚度與覆蓋構件45的厚度幾乎相同， 以觸控面板4的厚度收於覆蓋構件45的厚度內的方式被 設定。亦即，觸控面板4被收容於覆蓋構件45的收容部 45a內，觸控面板4的主面4s與覆蓋構件45的主面45s 在側剖視圖被配置於幾乎水平的位置。在覆蓋構件45的 主面45s與薄膜構件30 (遮光膜46 )之間被設有圖示省 略的黏接劑，此外，在觸控面板4的主面4s與薄膜構件 30之觸控面板4側之面，被設有光學黏接二者之黏接劑 4 1，分別黏接著薄膜構件30與覆蓋構件45、觸控面板4 與薄膜構件3 0。 結果，如圖1 ( a )所示，支撐觸控面板4與覆蓋構件 4 5的薄膜構件3 0的表面成爲沒有階差的平坦面。總之， 觸控面板4的主面4s與覆蓋構件45的主面45s之間成爲 大致沒有階差產生的構成。 觸控面板4’藉由在兩枚基板8a、8b的周緣部設爲環 狀的密封材9而使具有特定的間隙而對向的前面側基板 (第1基板）8a與背面側基板（第2基板）8b黏接一體 化。 如圖3所示’觸控面板4的前面側基板8a，係於透明 基材之基板本體1 1 a的內面（背面側基板側之面）上，被 形成由透明導電材料所構成的一樣的平面形狀之面狀電極 -14- 200903074 (高電阻膜；第1電極）12a，於面狀電極12a之圖示Υ 方向兩端部（矩形狀的面狀電極12a之對向的兩邊端部） 被形成一對低電阻膜1 3之構成。被形成於前面側基板8a 的低電阻膜1 3，透過導通材1 7，被導電接續於形成在背 面側基板8b上的輔助電極18，進而透過該輔助電極18被 拉出至端子部1 6。低電阻膜1 3、1 4以及輔助電極1 8構成 觸控面板4的配線部，沿著基板8a或者基板8b之周緣部 被形成。 另一方面，觸控面板4的背面側基板8 b，係於透明基 材之基板本體1 1 b的內面（前面側基板側之面）上，被形 成由透明導電材料所構成的一樣的平面形狀之面狀電極 (高電阻膜；第2電極）12b，於面狀電極12b之圖示X 方向兩端部（矩形狀的面狀電極1 2b之對向的兩邊端部） 被形成一對低電阻膜1 4之構成。於背面側基板8b之邊端 部，被形成與從低電阻膜1 3及低電阻膜1 4拉出的配線相 連接的端子部1 6。 於端子部16，如圖1所示，可撓印刷電路板透過 ACP( Anisotropic Conductive Paste，向異性導電漿）或 ACF( Anisotropic Conductive Film，向異性導電膜）被連 接，使端子部1 6與外部的控制電路導電連接。 於本實施型態，前面側基板8 a的外側面，且對應面 狀電極12a的形成區域之平面區域係座標輸入面（成爲藉 由輸入器具3或手指等直接指示觸控面板上的位置進行輸 入操作的操作面之前述輸入部40a)。 -15- 200903074 於構成前面側基板8a與背面側基板8b的基板 1 1 a、1 1 b，均使用硬質之玻璃基板。藉由使前面側基 爲玻璃基板，變得不會像把塑膠基板用於前面側基板 合那樣會產生基板或電極的劣化的問題。另一方面’ 的玻璃基板比塑膠薄膜基板還要缺乏柔軟性，所以輸 的加壓荷重太小的話，會有不能充分進行輸入的問題 此，在本實施型態，使玻璃基板的厚度薄化到〇.11 0.2 m m程度而解消操作性的問題。另一方面，作爲構 面側基板8 b的基板本體1 1 b，使用與液晶面板等同樣 者。例如，在本例，使觸控面板4的背面側基板8 b 度爲0.5mm程度。 面狀電極12a、12b係由ITO (銦錫氧化物）等 明導電膜所構成，在其面內全區域具備幾乎均一之 阻。此外，低電阻膜1 3、14、輔助電極1 8以及端 1 6，係由導電性高的金屬薄膜’例如 Au、Ag、Cu、 Cr、或者包含這些金屬之中的任何一種類以上的合金 成。 在本實施型態，作爲前面側基板8 a以及背面側 8b之基板本體使用玻璃基板，所以與使用塑膠薄膜基 從前的觸控面板不同，可以進行高溫熱處理或使用強 蝕刻溶液之蝕刻處理。因此，在本實施型態’檢測出 資訊之用的這些導電膜（面狀電極1 2a、i 2b、輔助 18、端子部16等）均使用濺鍍法或者蒸鍍法等真空 來形成，進而藉由飩刻處理使低電阻膜1 3、1 4以及 本體 板8 a 的場 硬質 入時 。因 ή m〜 成背 厚度 的厚 之透 面電 子部 A1、 所形 基板 板的 酸性 座標 電極 製程 輔助 -16- 200903074 電極1 8細線化’形成窄框緣之配線部。例如，於配線部 使用APC ( AgPdCu合金，比電阻爲4xl〇-6Qcm程度）的 場合，從前以銀漿製作的厚度2 0 μιη、線寬1 mm的拉回配 線’在 A P C能夠做成厚度0.2 μ m、線寬0 _ 1 m m。此外， 銅、鋁、鉻之比電阻（Dcm )，分別爲6χ10·6、6χ1(Γ6、5 X 1 0_5程度，所以即使使用這些金屬，也可使線寬與從前 相比還要細窄化1到2個數量級。 於背面側基板8 b之面狀電極1 2 b上，被排列形成樹 脂材料等所構成的緩衝構件1 5。緩衝構件最好使用矽樹脂 或氨基甲酸乙酯等彈性材料（例如，彈性率在1 X 1 〇4N/m2 〜1x10 8N/m2之範圍），使用光蝕刻法或印刷法形成在面 狀電極1 2 b上。此緩衝構造，亦作爲控制基板8 a、8 b之 間隙之用的間隔件而發揮功能。 作爲被黏接於觸控面板4上的薄膜構件30，可以使用 PET ( polyethylene terephthalate，聚對苯二甲酸乙二醇 酯）等聚乙烯、聚酯、聚丙烯等透明樹酯材料所構成之薄 膜材。在輸入裝置40A，對觸控面板4進行座標輸入操作 時以輸入器具3或手指等在薄膜構件30的表面滑動，或 者也在觸控面板4的背面側（薄膜構件3 0之相反側）配 液晶面板等顯不手段而作爲顯示裝置使用。因此，作爲 薄膜構件3 0，最好是可以良好地防止由於操作導致磨耗， 或者覆蓋構件4 5或觸控面板4的表面之損傷，此外最好 疋可以得到良好的透過率者。 作爲設在薄膜構件3 0與觸控面板4之間的黏接劑 -17- 200903074 (黏著劑），可以使用壓克力系、橡膠系、矽樹酯等種種 黏接劑。在本實施型態，因爲光學黏接薄膜構件3 0與觸 控面板4，所以最好使用矽樹酯系之黏接劑。 被形成於薄膜構件30的覆蓋構件45側面之遮光膜 4 6，例如係藉由印刷而塗布黑色材料或白色材料而被形成 之著色膜。在本實施型態的場合，被形成觸控面板4的密 封材9的區域，或被形成端子部16的部分之作爲遮蔽物 而發揮功能，在觸控面板4的背面側（薄膜構件3 0的相 反側）設置液晶面板等顯示手段的場合也作爲對顯示之周 邊遮蔽物而發揮功能。遮光膜46只要具有遮光性即可， 可使用任意之顏色，附有圖案亦可。 在薄膜構件30，不僅前述遮光膜46而已，可施以任 意之色彩、模樣所構成之設計。相關的設計也可以形成於 薄膜構件3 0的任一面，但由保護印刷物的觀點來看，最 好被形成於覆蓋構件45側。 覆蓋構件4 5，係由塑膠板或金屬板所構成者，只要是 具備特定的強度之基材即可，並無特別要求。此覆蓋構件 4 5，不僅作爲觸控面板4的支撐體，例如可以作爲構成電 子機器的操作面板的構件來使用，在此場合，可以作爲觸 控面板內藏之操作部來使用。此外作爲電子機器的操作部 而利用輸入裝置40A的場合’亦可在覆蓋構件45設置操 作按鈕或開關用之貫通孔，這樣的加工可以藉由衝壓或削 出而容易達成。進而，可以在薄膜構件3 0施以印刷，所 以可印刷按鈕或開關的說明等文字資訊。 -18- 200903074 在具備前述構成的本實施型態之輸入裝置4〇A ’具備 在被形成在覆蓋構件45的收容部45&內配置觸控面板4 ’ 跨觸控面板4的主面4s與覆蓋構件45的主面45s而黏接 薄膜構件3 0的構成’解消了觸控面板4的輸入操作面與 其外側之覆蓋構件4 5表面之間的階差。藉此’與從前相 比可以提高設計的自由度，成爲可得優異的新式樣性之輸 入裝置。 此外，如從前那樣在觸控面板與筐體之間有階差的場 合，會有在該階差累積灰塵’或者有水滴附著時水滴從階 差部分的間隙浸入筐體內之問題產生’但在本實施型態， 包含覆蓋構件45的全面都以薄膜構件30覆蓋，所以不會 有累積灰塵損及美觀，或者水滴浸入成爲故障原因等情形 發生，而成爲可信賴性優異的輸入裝置。 此外，於厚度〇.1〜〇.2mm程度的薄型玻璃基板所構 成的觸控面板4的前面側基板8 a透過黏接劑4 1而被貼附 薄膜構件3 0，所以即使因落下或異物之衝擊而使前面側基 板8a破裂的場合，也可以藉由薄膜構件30防止玻璃碎片 的飛散，可實現安全性優異的輸入裝置。特別是在本實施 型態，薄膜構件3 0以覆蓋包含觸控面板4與覆蓋構件45 的一面的方式被黏接，所以薄膜構件30極難剝離，這一 點也使其具有優異的安全性。 進而，在本實施型態之輸入裝置40A，觸控面板4係 被配置於貫通覆蓋構件45而設的收容部45a內。亦即， 覆蓋構件45成爲不限制觸控面板4之基板厚度方向的移 -19- 200903074 動。亦即，即使在觸控面板4的厚度上產生製造上差異， 也可以薄膜構件3 0的表面成爲平坦的方式使觸控面板4 與覆蓋構件45黏接於薄膜構件30。 此處，說明觸控面板4之輸入操作。 於觸控面板4，在端子部1 6被連接輸入控制電路（省 略圖示），藉由該輸入控制電路，在某個時間點，對位於 背面側基板8 b之X方向的兩端部之低電阻膜1 4、1 4之間 施加特定的電壓，在位於前面側基板8 a之Y方向的兩端 部之低電阻膜1 3、1 3間被導電連接前述輸入控制電路內 之電壓測定手段（電壓測定電路或者電壓測定元件，省略 圖示）。於此時間點，在背面側基板8b之面狀電極1 2b， 沿著X方向產生直線性改變電壓的均一之電壓降下，構成 X方向之等於位置座標軸的部位彼此幾乎成爲相同電位的 電壓分佈。此時前面側基板8a之座標輸入面的某個部位 被以輸入器具3之先端按壓的話，前面側基板3a之面狀 電極12a與背面側基板8b之面狀電極12b接觸，通過前 面側基板8a之面狀電極12a，藉由輸入器具3被按壓的前 述部位所對應的位置之面狀電極12b的電壓係藉由輸入控 制電路來測定。此被測定之値，與被按壓的部位之X方向 的位置座標相關，所以輸入控制電路可以檢測出以輸入器 具3按壓的部位的X方向之位置。 另一方面，在其他之某個時間點，藉由輸入控制電路 對位於前面側基板8 a之Y方向的兩端部之低電阻膜1 3、 1 3之間施加特定的電壓，在位於背面側基板8b之Y方向 -20- 200903074 的兩端部之低電阻膜1 4、1 4間成爲前述電壓測定手段被 連接的狀態。於此時間點，在前面側基板8 a之面狀電極 12a，沿著Y方向產生均一的電壓降下，形成直線狀電壓 改變的電壓分佈。前述之輸入控制電路，藉由通過背面側 基板8b的面狀電極1 2b檢測出對應於以輸入器具3按壓 的部位之位置的前面側基板8 a的面狀電極1 2 a之電壓， 與關於前述之X方向的位置的場合同樣，可以檢測出按壓 部位的Y方向的位置。 藉由在短時間內反覆進行對輸入控制電路之前述2個 連接狀態的切換，輸入控制電路，可以檢測出藉由輸入器 具3按壓的部位之X方向的位置座標値以及Y方向的位 置座標値。 此外，在本實施型態之觸控面板4，具有藉由密封材 使兩枚玻璃基板黏接一體化的構造，所以可以基本上可藉 由與製造液晶面板同樣的方法來製造。因此，作爲使用於 觸控面板4的製造之基板本體，只要使用與液晶面板之2 枚基板約略相同厚度者，即可使觸控面板4之生產線與製 造液晶面板之生產線共通化。但是，針對前面側基板8a 爲了座標輸入操作的緣故而有必要薄型化賦予可撓性，所 以在貼合〇.5mm程度的厚度之2枚基板後，對一方之基板 施以蝕刻處理使其薄化爲0.1mm〜0.2mm程度即可。從製 造步驟之最初就使用薄化的基板的話，基板的操作不易’ 可能會在製造步驟中發生基板的破裂等，對機械衝擊的耐 受性也很差。如前所述在透過密封材9貼合之後僅使前面 -21 - 200903074 側之基板本體1 1 a薄化，可以有效地防止在這樣的製造步 驟之不良情形的發生。 [第2構成例] 另一方面，在圖1 (b)所示之輸入裝置40B，除了在 觸控面板4與薄膜構件3 0之間的黏接劑4 1以外，在觸控 面板4與覆蓋構件45的收容部45a的內壁部之間，塡充 黏接劑42成爲包圍觸控面板4的框狀。亦即，觸控面板4 被固定於薄膜構件30與覆蓋構件45雙方。 接著’根據在觸控面板4與覆蓋構件4 5之間被配設 黏接劑42的輸入裝置40B，除了可以得到與先前說明的 輸入裝置4 0 A同樣的作用效果以外，還可以得到以下的作 用效果。 亦即’觸控面板4被支撐於覆蓋構件45在基板面方 向及基板厚度方向之任一之方向的移動都被限制住，所以 可避免由於觸控面板4的輸入操作而使觸控面板4被壓陷 入深處’或者由於落下的衝擊而使觸控面板4在收容部 4 5 a內移動’可使其成爲操作性及耐久性優異的輸入裝 置。 [第3構成例] 其次’圖4(a)係第丨實施型態之輸入裝置之第3構 成例之輸入裝置40C的槪略剖面圖。圖4 ( b )係顯示輸 入裝置40C的平面構成之圖。圖4(a)係相當於圖1 -22- 200903074 (a)及圖1 (b)之圖，圖4(b)係相當於圖2之圖 本例之之輸入裝置40 C與第2構成例之輸入裝置 之不同點’在於跨覆蓋構件45與觸控面板4而被形 薄膜構件3 0被形成開口部3 0 a這一點有所不同。亦 於圖4對與圖1之共通的構成要素，賦予相同符號而 詳細說明。 如圖4所示，薄膜構件3 0的開口部3 0 a，係沿著 疊於觸控面板4的周緣部被形成的遮光膜46的開口咅| 的端緣被形成爲矩形狀’對應於成爲觸控面板4的輸 作部的平面區域而開口。亦即，在輸入裝置40C，在 側基板8 a上使直接輸入器具3或者手指滑動，而進 觸控面板4之輸入操作。 具備前述構成之本例之輸入裝置4 0C因爲將前面 板直接按壓而進行對觸控面板4之輸入操作，所以與 薄膜構件3 0進行輸入操作的第1實施型態之輸入 40A、40B相比操作壓力變低，可以進行舒適的輸 作。 又，在本例，部分除去薄膜構件3 0而形成開 3 0a，所以薄膜構件30與觸控面板4透過黏接劑41 的區域係觸控面板4(前面側基板8a)的周緣區域。 緣區域之寬幅，雖隨觸控面板4之尺寸而不同’但通 少可以確保數mm程度，所以可以確保薄膜構件3 0 控面板4之黏接強度。但是’與圖1所示之輸入 4 0 A、4 0 B比較的話黏接面積狹窄’黏接強度變低’ 40B 成的 即， 省略 以重 )4 6a 入操 前面 行對 側基 透過 裝置 入操 口部 黏接 此周 常至 與觸 裝置 所以 -23- 200903074 於本例之輸入裝置40C’與輸入裝置40B同樣’於觸控面 板4與覆蓋構件4 5之間隙配設黏接劑4 2而黏接覆蓋構件 45與觸控面板4爲較佳。 此外在本例之場合’如圖4所市’被形成於薄膜構件 30的覆蓋構件45側的遮光膜46，最好是形成於薄膜構件 30的開口部30a的外側，藉由黏接薄膜構件30與觸控面 板4之黏接劑4覆蓋遮光膜46的構成。藉由如此般構 成，開口部30a內不再露出遮光膜46，所以可以防止由遮 光膜46與薄膜構件30之界面產生剝離，此外可以有效果 地保護遮光膜46。 進而，在本例的場合’因爲是觸控面板4之前面側基 板8 a露出的構造，所以前面側基板8 a的基板本體1 1 a如 果是玻璃基板的話，會有由於落下等之衝擊而使玻璃基板 破損時破片會四處飛散之虞。亦即，採用如本例所示之構 成的場合，作爲前面側基板8 a之基板本體1 1 a最好是使 用高強度之玻璃基板或塑膠基板。或者是，在基板本體 1 1 a的表面塗布透明樹脂等形成保護層較佳。 [第4構成例] 圖5係第1實施型態之輸入裝置之第4構成例之輸入 裝置4 0 D的槪略剖面圖，係相當於圖1 ( a )及圖1 ( b ) 之圖。 如圖5所示，本構成例之輸入裝置4〇D，具備相關於 第2構成例之輸入裝置40B爲基本構成，進而，於薄膜構 -24- 200903074 件30的覆蓋構件45側被配設偏光板6a。偏光板6a，可 以利用作爲被配設於觸控面板4的背面側（與薄膜構件3 0 相反之側）的液晶面板等之顯示手段的光學元件。 根據具備前述構成之輸入裝置40D，因爲在觸控面板 4的前面側被配設偏光板6a與薄膜構件30，所以與僅有 薄膜構件3 0的場合相比觸控面板4的操作壓力增加，而 觸控面板4的保護更爲確實。此外，具備玻璃基板的觸控 面板4破損時也更可有效地防止玻璃的飛散。 又，在本例係將偏光板6a配置於薄膜構件3 0與遮光 膜46之間，但將偏光板6a配置於遮光膜46與覆蓋構件 45之間亦可。或者是將偏光板6a與觸控面板4同時配置 於收容部45a內。進而，在偏光板6a具有充分的耐久性 的場合，不設置薄膜構件30而將偏光板6a作爲與觸控面 板4及覆蓋構件45黏接的可撓性構件使用亦可。 此外，在薄膜構件3 0與覆蓋構件4 5之間，不限於偏 光板，亦可配置其他光學元件。例如亦可配置層積偏光板 6a與λ/4相位差板，或者層積偏光板6a與λ/4相位差板 與λ/2相位差板之光學元件（圓偏光板）。進而，配置防 反射膜或光擴散膜亦可。 [第5構成例] 圖6 ( a ) ’係第1實施型態之輸入裝置之第5構成例 之輸入裝置40E的槪略剖面圖。圖6 ( a )係相當於圖1 (a)及圖1(b)之圖。 -25- 200903074 如圖6(a)所示，本構成例之輸入裝置40E，具備相 關於第2構成例之輸入裝置4 0B爲基本構成，進而，以從 觸控面板4的背面側（與薄膜構件3 0相反之側）覆蓋觸 控面板4與覆蓋構件45的方式被黏接薄膜構件3 1 (第2 可撓性構件）。 又，針對由觸控面板4拉出端子的可撓印刷電路板 1 6a，透過被設於薄膜構件3 1的狹縫狀開口部拉出至外 側。 作爲薄膜構件3 1，與薄膜構件3 0同樣，可以使用 PET ( polyethylene terephthalate，聚對苯二甲酸乙二酉手 酯）等聚乙烯、聚酯、聚丙烯等透明樹酯材料所構成之薄 膜材。藉由黏接薄膜構件可以防止輸入裝置40E全體的厚 度增大。 薄膜構件3 1，最好與觸控面板4的背面側基板3 b及 覆蓋構件45雙方黏接，薄膜構件31與觸控面板4最好被 光學黏接。但是，至少薄膜構件3 1與覆蓋構件45被黏接 的話，藉由薄膜構件3 1與薄膜構件3 0限制觸控面板4的 基板厚度方向之移動，所以薄膜構件3 1與觸控面板4沒 有被黏接，甚至薄膜構件3 1與觸控面板4之間係空隙亦 可。 根據具備前述構成之輸入裝置40E，成爲在觸控面板 4的背面側被配設薄膜構件3 1而藉由薄膜構件3 0、3 1夾 住觸控面板4的構成，所以對觸控面板4進行輸入操作 時，可以防止藉由輸入器具3或手指等之按壓力使觸控面 -26- 200903074 板4被按壓陷入。 又，作爲薄膜構件3 1，除了前述之透明薄膜以外，亦 可爲偏光板或相位差板。進而’不限於單體的光學元件， 亦可配置層積偏光板與λ/4相位差板’或者層積偏光板與 λ/4相位差板與λ/2相位差板之光學元件（圓偏光板）。 進而，配置光擴散膜亦可。 [第6構成例] 圖6 ( b )，係第1實施型態之輸入裝置之第6構成例 之輸入裝置40F的槪略剖面圖。圖6 ( b )係相當於圖1 (a)及圖1 (b)之圖。 如圖6 ( b )所示，本構成例之輸入裝置40F，具備相 關於第5構成例之輸入裝置40E爲基本構成，進而，係在 被黏接於觸控面板4的背面側（與薄膜構件3 0相反之 側）的薄膜構件31 (第2可撓性構件）被形成開口部3 1 a 的構成。開口部3 1 a，被形成爲具備與遮光膜46之開口部 46a平面俯視幾乎一致的平面區域。 根據具備前述構成之輸入裝置40F，成爲在觸控面板 4的背面側被配設薄膜構件31而藉由薄膜構件3 0、3 1夾 住觸控面板4的構成，所以對觸控面板4進行輸入操作 時，可以防止藉由輸入器具3或手指等之按壓力使觸控面 板4被按壓陷入。 此外，因被形成開口部3 1 a，例如在觸控面板4的背 面側配置液晶面板等顯示手段的場合，成爲在透過觸控面 -27- 200903074 板4進行顯示的區域沒有被配設薄膜構件31的構成，所 以不會產生由於薄膜構件3 1而導致光損失或折射，以及 在界面之反射 '可以得到明見的筒品質的顯不。 在本實施型態的場合，在薄膜構件3 1被形成開口部 31a，所以薄膜構件31成爲支撐觸控面板4的周緣部的構 造。亦即，最好以藉由薄膜構件3 1安定地支撐觸控面板4 的方式，黏接薄膜構件3 1與觸控面板4之背面側基板 8b ° 又，以上之實施型態係舉例顯示相關於本發明的輸入 裝置的構成，針對各構成要素之構成可以加以種種的變 更。 例如’觸控面板4，可以做成具備藉由前面側基板 8 a、背面側基板8 b、以及密封材9所包圍的空間內封入折 射率調整用的液狀材料之緩衝構造的構成。作爲封入前面 側基板8a與背面側基板8b之間的液狀材料，最好使用與 玻璃之折射率差比空氣還要小的矽油等。 如此般封入液狀材料的話，在此觸控面板的背面側配 設液晶面板等顯示手段的場合’可以防止由顯示手段射出 的光在背面側基板8b與前述空間或者前述空間雨前面側 基板8 a之界面反射，所以可實現透過觸控面板4之明亮 的顯示。 此外，藉由在基板間封入液狀材料，這可以作爲一種 緩衝器而發揮功能，對前面側基板8 a施加衝擊時，可以 使它緩和。總之，在本實施型態，因爲使前面側基板8a -28- 200903074 的座標輸入面比其他部分的板厚還要薄’雖然比通常的在 機械衝擊上抵抗力較弱’但設置這樣的緩衝構造藉由補強 該部分可以彌補其耐衝擊性。考慮前述緩衝功能的話’液 狀材料的黏度例如在2mm2/s〜5000mm2/s之範圍。 此外，另行考慮的話’可以替代電阻膜方式之觸控面 板4，而使用靜電電容方式之觸控面板。靜電電容方式的 觸控面板的場合，其厚度只要玻璃基板1枚的厚度就大致 足夠，可以使覆蓋構件4 5的收容部4 5 a，或者使覆蓋構件 45自身薄化，所以可謀求輸入裝置40A、40B全體的薄型 化。 此外在本實施型態說明在貫通覆蓋構件4 5而形成的 收容部45a內收容觸控面板4的構成，但針對收容部45a 的構造，可藉由觸控面板4的形狀或厚度來進行種種變 更。例如，亦可在覆蓋構件45設置往收容部45a內突出 的突起等卡止構件，藉由相關的卡止構件來限制觸控面板 4之基板厚度方向的移動。 此外，在使用於不在觸控面板4的背面側配設顯示手 段的用途的場合，收容部45a亦可爲被形成於覆蓋構件45 的一面側之凹部。只要在由這樣的凹部所構成的收容部 45a內配置觸控面板4，觸控面板4的位置限制變得極爲 容易’此外跨觸控面板4與覆蓋構件45而被黏接的薄膜 構件3 0的表面的平坦性也變得容易確保。 [第2實施形態] -29- 200903074 其次，參照圖7至圖9說明本發明之第2實施型態之 光電裝置。 圖7 ( a )係顯示相關於第2實施型態之光電裝置之— 例之觸控面板一體型之液晶裝置之第1構成例之槪略剖面 圖。圖8同樣係第2構成例之液晶裝置的槪略剖面圖。圖 9同樣係第3構成例之液晶裝置的槪略剖面圖。 又，在本實施型態作爲具備於液晶裝置的輸入裝置舉 相關於第1實施型態之第2構成例之輸入裝置40B、或者 相關於第4構成例之輸入裝置40D來說明，但取代輸入裝 置40B、40D而使用其他構成例之輸入裝置40A、40C、 40E、40F 亦可。 [第1構成例] 相關於圖 7 ( a )所示之第1構成例的液晶裝置 1 00A，被構成爲具備：顯示部之液晶面板（光電面板） 2，被配設於其前面側（圖示上側；觀察側）之第1實施 型態的輸入裝置40B。 輸入裝置40B，如前所述，具備：類比型電阻膜方式 之觸控面板（輸入面板）4，具備收容觸控面板4的收容 部45a之覆蓋構件45，覆蓋觸控面板4及覆蓋構件45而 與覆蓋構件45的主面45s與觸控面板4的主面4s黏接之 薄膜構件3 0。 液晶面板2，藉由包含透光性的彈性體（例如，與玻 璃之折射率差比空氣還要小的矽凝膠、壓克力凝膠、氨基 -30- 200903074 甲酸乙酯凝膠、氨基甲酸乙酯橡膠等透光性之彈性體）的 黏接劑50，與觸控面板4的背面側基板8b光學黏接。以 藉由彈性體構成黏接劑5 0，使彈性體吸收對觸控面板4進 行輸入操作時之按壓力，可以抑制由於輸入操作所導致液 晶面板2的基板因應變（strain)而導致顯示不良。彈性 體因爲吸收按壓力，所以其後度以5 0〜5 0 0 μπι較佳。 此外，使其與觸控面板4的背面側基板8b光學接 續，所以在與觸控面板4之背面側基板8 b之間的間隙 (空氣層）不再形成。黏接劑5 0因與玻璃之折射率差比 空氣還要小，例如由觸控面板4的前面側基板（第1基 板）側入射的環境光之中，可以抑制在觸控面板4之背面 側基板（第2基板）lib之表面與空氣層之界面反射的 光，以空氣層與液晶面板2的前面側基板（第3基板） 22a之表面之界面反射的光的產生，成爲可進行反射很少 的鮮明的顯示。爲了得到這樣的效果，有必要使被包含於 黏接劑5 0的彈性體之折射率，接近於構成觸控面板4及 液晶面板2的玻璃基板或者塑膠基板的折射率，折射率最 好在1.4〜1 . 9。 液晶面板2，藉由在兩枚基板的周緣部設爲環狀的密 封材2 3而使挾著液晶（光電物質）3 2而對向的前面側基 板（第3基板）22a與背面側基板（第4基板）22b黏接 —體化。被配置於觀察側的前面側基板22a，在透明基板 之基板本體24 a的液晶層側之面上，具有形成由透明導電 材料所構成的前面側電極26a或配向膜（省略圖示）等的 -31 - 200903074 液晶控制層之構成。被配置於觀察側的相反側（挾著 層32雨前面側基板22a相反之側）的背面側基板22b 透明基板之基板本體Mb的液晶層側之面上’具有形 透明導電材料所構成的背面側電極26b或配向膜（省 示）等的液晶控制層之構成。 在前面側基板22a與背面側基板22b之間’使 22a、22b間的距離（胞間隙）保持一定之用的粒狀間 29被分散配置。液晶面板2，可以爲被動矩陣型或主 陣型之任一，液晶的配向型態，也可以採用TN型、 型、S TN型、強介電型、反強介電型等種種習知的型 此外，也可以在任一之基板配置彩色濾光片而使進行 顯示。進而，於背面側基板22b形成反射膜而構成反 之液晶顯示裝置亦可，於此反射膜形成開口部或狹縫 光部，構成半透過反射型之液晶顯示裝置亦可。 於前面側基板22a，被設有往背面側基板22b的 側伸出的伸出部24c。此伸出部24c係作爲實裝端子 區域來使用的。在伸出部24c被形成省略圖示的配 案，前面側基板2 2 a的前面側電極2 6 a、以及背面側 22b之背面側電極26b，透過省略圖示的配線圖案或 材被導電連接於伸出部2 4 c之配線圖案。接著，對伸 24c之配線圖案，被COG實裝導電驅動液晶面板2之 驅動用1C (電子零件）36。作爲液晶驅動用1C 36的 型態，除了 COG實裝以外，也可以採用FPC實裝等 型態。 液晶 ，在 成由

域也藉由遮光膜46而遮住。此外’可以使觸控面板4的 背面側基板8 b與液晶面板2之前面側基板2 2 a重疊的區 域成爲最大’所以可以提局觸控面板4與液晶面板2之黏 接可信賴性。此外’對外部電路之接續端子被形成的區域 係觸控面板4與液晶面板2接近而配置’所以對外部電路 之接續可以容易地進行。 又，在圖面雖然省略，但在液晶面板2的前面側基板 22a的外面側、以及背面側基板22b的外面側，分別被設 有偏光板。這一對偏光板，任一方亦可被設於基板本體 24a或基板本體24b之液晶層32側。此外，於背面側基板 22b之外側被配設照明裝置（背光）。 根據具備以上的構成之本例的液晶裝置1 〇〇A，因爲 具備第1實施型態之輸入裝置40 B、與輸入裝置4 0 B之觸 控面板4黏接之液晶面板2，所以可進行透過觸控面板4 的顯示。 此外，藉由在觸控面板4的背面側配置液晶面板2， 觸控面板4的基板厚度方向之移動受到液晶面板2或支撐 液晶面板2的筐體等限制，而可以使不會因在輸入操作時 之按壓力而使觸控面板4被按壓陷入。 接著，在本實施型態之液晶裝置，顯示面側藉由薄膜 -33- 200903074 構件3 0而成爲平坦面，此外在薄膜構件3 0可以施以任 的印刷，所以設計上的自由度很高’成爲可得到優異的 式樣性之液晶裝置。 此外在本實施型態之液晶裝置’於觸控面板4的前 側被配設薄膜構件3 0，所以可以安全地使用在前面側基 8a用了玻璃基板的觸控面板4。於2枚基板本體11a、1 之雙方使用玻璃基板之觸控面板，與基板本體lla爲塑 基板者，或者與基板本體lla、llb雙方均爲塑膠基板 相比可得高透過率，所以與從前相比可得到明亮且高畫 的顯示。 又，在本實施型態，液晶面板2成爲由覆蓋構件 突出的構成，但只要覆蓋構件45具有充分的厚度’使 晶面板2與觸控面板4 一起收容於覆蓋構件45之收容 45a內亦可。採用這樣的構成的話，可以於覆蓋構件45 液晶面板2之間配設黏接劑而黏接二者’所以可以藉覆 構件45安定地支撐觸控面板4與液晶面板2之雙方。 而，於液晶面板2的背面側（與觸控面板4相反之側） 備背光的場合，也可以使其成爲在收容部4 5 a收容相關 背光之構成。 然而，在如本實施型態這樣於液晶面板2之前面側 置觸控面板4的構成’以手指或輸入器具3按壓觸控面 4的表面而進行輸入操作時’會使液晶面板2的顯示產 失真。這是因爲藉由輸入時之按壓力使在觸控面板4產 局部的變形，藉由此變形’使設在觸控面板4的背面側 新 面 板 lb 膠 者 質 4 5 液 部 與 蓋 進 具 的 設 板 生 生 之 -34- 200903074 液晶面板2之前面側基板發生非常少量的撓曲。總 晶面板2的間隙爲1 μιη〜1 0 μιη程度，所以即使前 板2 2a之撓曲僅有些許而已，但此撓曲使液晶面板 隙局部地以大比率變動，結果，於顯示產生像是干 扭曲。 這樣的問題，可以藉由使液晶面板2的背面 22b的厚度充分變薄而解決。例如，使背面側基板 厚度薄化至 0.1mm〜0.4mm程度而使基板容易撓 合，如前所述即使在液晶面板2之前面側基板22a 曲，追隨著該撓曲背面側基板22b也跟著撓曲’間 幾乎不變動。但是，如此般使基板薄化的話，基板 變得不易，可能會在製造步驟中發生基板的破裂 外，對機械衝擊的耐受性變差，所以在攜帶用途中 場合，也會發生由於落下等而導致破損的問題。 行，在基板的操作性或耐衝擊性之面，基板是越厚 在顯示品質之面向，則是基板越薄越好。 此處爲了滿足雙方的要求，可以採用如圖7(b 的構成之液晶面板2A。在相關的液晶面板2A ’於 基板22a使用厚板之玻璃基板提高操作性等，另一

[第2構成例] 其次，參照圖8說明本實施型態之第2構成例。 如圖8所示，第2構成例之液晶裝置1 00Β，具備第1 實施型態之輸入裝置40Β，與液晶面板2Β。液晶面板 2Β，於其基本構成與相關於第1構成例之液晶面板2Α共 通，僅面板尺寸有所不同。具體而言，液晶面板2 Β，成 爲前面側基板22a具有比覆蓋構件45之收容部45a還要 大的平面面積之基板。 接著，液晶面板2B透過黏接劑50與觸控面板4的背 面側基板8b黏接，且也與覆蓋構件45之內面45b黏接。 覆蓋構件45與液晶面板2之黏接方法，除了在覆蓋構件 4 5與液晶面板2之間另行塗布黏接劑而黏接的方法以外， 可以採用使黏接劑50延伸設置至覆蓋構件45上而藉由黏 接劑5 0黏接覆蓋構件4 5與液晶面板2之方法，或使黏接 觸控面板4與覆蓋構件4 5之黏接劑4 2延伸出至覆蓋構件 45的背面45b上而黏接的方法。 -36- 200903074 在具備前述構成的本例之液晶裝置100B’被配設於 觸控面板4的背面側之液晶面板2之前面側基板2 2 a，因 爲與覆蓋構件45之背面45b黏接，所以觸控面板4被固 定於以薄膜構件30與液晶面板2與覆蓋構件45包圍的空 間，被保持安定。 又，於圖8所示之第2構成例，也可以省略使液晶面 板2與觸控面板4黏接的黏接劑50。 在圖8所示之第2構成例，液晶面板2與觸控面板4 與覆蓋構件45，透過黏接劑50以及黏接劑42等而相互黏 接，所以成爲最安定地支撐被液晶面板2與觸控面板4的 構造。另一方面，如此般在以黏接劑黏接各部的構成，因 爲工數很多，另外原物料也多有要求。爲此，在本構成 例，藉由省略黏接觸控面板4與液晶面板2之黏接劑5 0， 成爲可以削減工數同時可廉價地製造液晶裝置的構成。 此外，如此構成的場合，於觸控面板4與液晶面板2 之間被形成間隙（空氣層），所以觸控面板4的輸入操作 時之按壓力變得很難加至液晶面板2。藉此，可以防止起 因於液晶面板2的扭曲之顯示不良的發生。 [第3構成例] 其次’參照圖9說明本實施型態之第3構成例。 相關於圖9所示的第3構成例之液晶裝置i〇〇c，於 相關於第1構成例之液晶裝置1 0 0 A，係改變偏光板的配 置態樣者。 -37- 200903074 如圖9所示，本構成例之液晶裝置1 〇 0

板的前面及背面之一對偏光板之中，被配置於前面側的 光板被配置於觸控面板4的外側。 根據具備前述構成之液晶裝置100 C，因爲在觸控 板4的前面側（與液晶面板2相反之側）被配設前面側 光板6a與薄膜構件3 0，所以與僅有薄膜構件3 0的場合 比觸控面板4的操作壓力增加，而觸控面板4的保護更 確實。此外，具備玻璃基板的觸控面板4破損時也更可 效地防止玻璃的飛散。 此外因爲把前面側偏光板6a配置於觸控面板4的 側，所以可使覆蓋構件4 5的收容部4 5 a起被配設於背 側（與薄膜構件3 0相反之側）的觸控面板4以及液晶 板2的合計厚度薄化。藉此，可以節省具備液晶裝 100C的電子機器之筐體內的空間，可謀求筐體的小 化。 入 成 的 ) 3 2 光 面 偏 面 偏 相 爲 有 外 面 面 置 型 -38- 200903074

部45A已由薄膜構件30側按壓觸控面板4的周緣部的方 式支撐觸控面板4。面板支撐部45A於觸控面板4上具有 矩形狀之開口部4 5 b。 於薄膜構件3 0之覆蓋構件4 5側，被形成例如藉由印 刷而形成的遮光膜4 ό ’遮光膜4 6於對應觸控面板4的輸 入部40a之平面區域內具有矩形狀之開口部46a。遮光膜 46係以平面俯視覆蓋住覆蓋構件45的方式被形成，遮光 膜46的開口部46a係以沿著面板支撐部45A的開口部 4 5 b的內周的方式被配置於比開口部4 5 b更爲內側。 觸控面板4的厚度與覆蓋構件45的收容部45a的深 度幾乎相同，觸控面板4在被收容進覆蓋構件45的收容 部4 5 a內的狀態，使觸控面板4的主面4 s與面板支撐部 45 A的內面（觸控面板4側之面）抵接。接著，於觸控面 板4之背面側（與薄膜構件3 0相反之側），被配設有跨 觸控面板4的背面（與薄膜構件3 0相反之側的面）與覆 蓋構件45的背面（與薄膜構件3 0相反側之面）而被黏接 之背面側薄膜構件3 1。亦即，於輸入裝置40A，觸控面板 4係以被框狀的面板支撐部4 5 A與背面側薄膜構件3 1所 挾持而被限制面板厚度方向的移動之狀態下被支撐於覆蓋 構件4 5。 又，針對由觸控面板4拉出端子的可撓印刷電路板 1 6a，透過被設於背面側薄膜構件3 1的省略圖示之狹縫狀 開口部拉出至外側。此外，作爲背面側薄膜構件3 1，與薄 -40- 200903074 膜構件 30 同樣，可以使用 PET ( polyethylene terephthalate，聚對苯二甲酸乙二醇酯）等聚乙烯、聚 酯、聚丙烯等透明樹酯材料所構成之薄膜材。 接著，平面俯視以覆蓋住覆蓋構件4 5與觸控面板4 的方式配置的薄膜構件3 0，以依循於被形成在覆蓋構件 45的主面45s，與露出於面板支撐部45A的開口部45b內 之觸控面板4的主面4s的邊界部之階差的形狀被黏接於 覆蓋構件45以及觸控面板4。 總之，在平坦面之覆蓋構件45以及面板支撐部45 A 上，還有在觸控面板4上，薄膜構件30的表面爲平坦 面。另一方面，於藉由面板支撐部45A的開口部45b所形 成的觸控面板4的主面4s與覆蓋構件45的主面45s之間 的階差部分，薄膜構件3 0變形而密接於構成階差的構件 的表面，結果，於薄膜構件30的表面也形成階差部43。 又，將於稍後詳述，但要如此般使薄膜構件3 0與觸 控面板4及覆蓋構件45密接，可以使用熱溶接法或真空 熱溶接法，藉由暫時使薄膜構件3 0軟化即可極爲容易地 進行。 觸控面板4，藉由在兩枚基板8a、8b的周緣部設爲環 狀的密封材9而使具有特定的間隙而對向的前面側基板 (第1基板）8a與背面側基板（第2基板）8b黏接一體 化。 如圖12所示，觸控面板4的前面側基板8 a，係於透 明基材之基板本體1 1 a的內面（背面側基板側之面）上， -41 - 200903074 被形成由透明導電材料所構成的一樣的平面形狀之 極（高電阻膜；第1電極）12a，於面狀電極12a Y方向兩端部（矩形狀的面狀電極1 2 a之對向的 部）被形成一對低電阻膜1 3之構成。被形成於前 板8a的低電阻膜13，透過導通材17，被導電接續 在背面側基板8b上的輔助電極18，進而透過該輔 18被拉出至端子部16。低電阻膜13、14以及輔助 構成觸控面板4的配線部，沿著基板8a或者基板 緣部被形成。 另一方面，觸控面板4的背面側基板8 b，係於 材之基板本體1 1 b的內面（前面側基板側之面）上 成由透明導電材料所構成的一樣的平面形狀之面 (高電阻膜；第2電極）12b，於面狀電極12b之 方向兩端部（矩形狀的面狀電極1 2b之對向的兩邊 被形成一對低電阻膜1 4之構成。於背面側基板8b 部，被形成與從低電阻膜1 3及低電阻膜1 4拉出的 連接的端子部1 6。 於端子部1 6，如圖1 0所示，可撓印刷電路 ACP( Anisotropic Conductive Paste，向異性導電 ACF( Anisotropic Conductive Film，向異性導電膜 接，使端子部1

於構成前面側基板8a與背面側基板8b的基板本體 1 1 a、1 1 b，均使用硬質之玻璃基板。藉由史前面側基板8 a 爲玻璃基板，變得不會像把塑膠基板用於前面側基板的場 合那樣會產生基板或電極的劣化的問題。另一方面，硬質 的玻璃基板比塑膠薄膜基板還要缺乏柔軟性，所以輸入時 的加壓荷重太小的話，會有不能充分進行輸入的問題。因 此，在本實施型態，使玻璃基板的厚度薄化到 0.1 mm〜 0.2mm程度而解消操作性的問題。另一方面，作爲構成背 面側基板8b的基板本體1 1 b，使用與液晶面板等同樣厚度 者。例如，在本例，使觸控面板4的背面側基板8b的厚 度爲0.5mm程度。 面狀電極12a、12b係由ITO (銦錫氧化物）等之透 明導電膜所構成，在其面內全區域具有幾乎均一之面電 阻。另一方面’低電阻膜13、14、輔助電極18以及端子 部16，係由導電性局的金屬薄膜》例如Au、Ag、Cu、 Al、Cr、或者包含這些金屬之中的任何一種類以上的合金 所形成。 在本實施型態，作爲前面側基板8 a以及背面側基板 8b之基板本體使用玻璃基板，所以與使用塑膠薄膜基板的 從前的觸控面板不同，可以進行高溫熱處理或使用強酸性 蝕刻溶液之蝕刻處理。因此，在本實施型態，檢測出座標 資訊之用的這些導電膜（面狀電極12a、12b、輔助電極 18、端子部16等）均使用濺鍍法或者蒸鍍法等真空製程 -43- 200903074 來形成，進而藉由蝕刻處理使低電阻膜1 3、1 4以及輔助 電極1 8細線化，形成窄框緣之配線部。例如，於配線部 使用APC(AgPdCu合金，比電阻爲4xlO_6Qcm程度）的 場合，從前以銀漿製作的厚度20μιη、線寬1mm的拉回配 線，在 A P C能夠做成厚度0.2 μ m、線寬0.1 m m。此外， 銅、鋁、鉻之比電阻（Qcm)，分別爲6χ10_6、6χ1(Γ6、5 X 1 〇 _5程度，所以即使使用這些金屬，也可使線寬與從前 相比還要細窄化1到2個數量級。 於背面側基板8 b之面狀電極1 2 b上，被排列形成樹 脂材料等所構成的緩衝構件1 5。緩衝構件最好使用矽樹脂 或氨基甲酸乙酯等彈性材料（例如，彈性率在1 X 1 04N/m2 〜1 X 1 08N/m2之範圍），使用光蝕刻法或印刷法形成在面 狀電極1 2 b上。此緩衝構造，亦作爲控制基板8 a、8 b之 間隙之用的間隔件而發揮功能。 作爲被黏接於觸控面板4上的薄膜構件3 0，可以使用 PET ( polyethylene terephthalate，聚對苯二甲酸乙二醇 酯）等聚乙儲、聚酯、聚丙儲等透明樹醋材料所構成之薄 膜材。在輸入裝置40A，對觸控面板4進行座標輸入操作 時以輸入器具3或手指等在薄膜構件30的表面滑動，或 者也在觸控面板4的背面側（薄膜構件3 0之相反側）配 設液晶面板等顯示手段而作爲顯示裝置使用。因此，作爲 薄膜構件3 0 ’最好是可以良好地防止由於操作導致磨耗， 或者覆蓋構件4 5或觸控面板4的表面之損傷，此外最好 是可以得到良好的透過率的P E T薄膜。 -44- 200903074 被形成於薄膜構件3 0的覆蓋構件4 5側

A的構造步驟之槪略剖面圖。圖1 3及圖1 4所示之剖面 構成’相當於沿著圖1 1所示之A-A ’線的位置之剖面構 成。 首先，如圖13 ( a)所示，準備具備收容部45a與面 板支撐部4 5 A的覆蓋構件4 5。覆蓋構件4 5，如果爲樹脂 材料所構成的話，可以藉由射出成形而容易製造具備收容 部45a及面板支撐部45A者。此外，如果爲金屬材料所構 成的話，可以藉由切削加工或衝壓加工而製造具備收容部 45a及面板支撐部45A者。 準備好覆蓋構件4 5時，把另行製作的觸控面板4，輸 入操作面之主面4s由被形成面板支撐部CA的相反側的 收容部45a之開口端側起嵌入收容部45a內。 作爲觸控面板4，因爲可使用從前習知的構造者’所 以針對其製造方法可以適用習知的製造方法。 使觸控面板4嵌入收容部45a時’如圖13(b)所 示，面板支撐部45A之開口部45b比觸控面板4的主面 4s還要窄，所以在觸控面板4的主面4s與面板支撐部 45A的背面45c抵接的狀態下觸控面板4被收容於收容部 45a內。此時，於面板支撐部45A的背面4SC與觸控面板 4的主面4 s之間設置黏接劑的話’僅使觸控面板4嵌入收 -48- 200903074 容部45a即可以相應的強度固定觸控面板4。 其後，如圖13 ( b )所示，使例如PET薄膜所構成的 背面側薄膜構件3 1跨覆蓋構件4 5與觸控面板4的背面側 基板8b而黏接。於背面側薄膜構件3 1的黏接，例如可以 使用矽樹脂系黏接劑。 藉此，被收容於收容部4 5 a內的觸控面板4，藉由被 黏接於其背面側（與面板支撐部4 5 A相反之側）的背面側 薄膜構件3 1，固定於覆蓋構件4 5。 其次，如圖1 3 ( c )所示，準備例如由PET薄膜所構 成的薄膜構件3 0。於薄膜構件3 0之成爲覆蓋構件4 5側的 面上，被印刷遮光膜4 6。接著，如圖1 3 ( d )所示，以使 印刷面朝向覆蓋構件45側的狀態，覆蓋覆蓋構件45以及 觸控面板4的方式配置薄膜構件30。此時，薄膜構件30 的表面之遮光膜46的開口部46a，以使遮光膜46的開口 部46a被配置於面板支撐部45A的開口部45b內的方式對 準位置。 其次’如圖1 4 ( a )所示’使用加熱裝置3 5 〇加熱薄 膜構件3 0，使薄膜構件3 0軟化，把薄膜構件3 〇熱溶接於 觸控面板4以及覆蓋構件4 5。作爲這樣的溶接方法，可以 使用熱板溶接、真空熱溶接、振動溶接、超音波溶接、雷 射溶接、衝擊溶接、高頻誘導加熱溶接、電磁誘導加熱溶 接、熱壓溶接等溶接方法。 如此一來，如圖1 4 ( b )所示，軟化的薄膜構件3 〇進 入面板支撐部45A的開口部45b內，以沿著觸控面板4的 -49- 200903074 主面4s、以及觸控面板4與覆蓋構件45之階差的方式 接於觸控面板4與覆蓋構件45。此外藉由此步驟，於薄 構件30的表面被形成跟隨於觸控面板4與覆蓋構件45 階差的形狀之階差部43。 如以上所說明的，根據本實施型態之製造方法，因 熱溶接薄膜構件3 0使對觸控面板4、以及對觸控面板4 覆蓋構件45之階差密接，所以觸控面板4與覆蓋構件 之階差可以藉由薄膜構件3 0緩和而可以簡便的步驟製 提筒設計自由度之輸入裝置40A。 此外，在被設於覆蓋構件45的收容部45a使面板 嵌入’進而因爲由觸控面板4的背面側黏接固定背面側 膜構件3 1 ’所以可以極爲簡便的步驟將觸控面板4固定 覆蓋構件45。 又，藉由在薄膜構件30的表面印刷遮光膜46等， 使薄膜構件3 0在熱溶接時無法確保薄膜構件3 〇的黏接 的場合，在對應於遮光膜46的形成區域的薄膜構件3 0 表面，或是在覆蓋構件45的表面配置黏接劑亦可。 [第2構成例] 在相關於圖1 〇 ( b )所示之第2構成例的輸入裝 40B，在觸控面板4與覆蓋構件45之間的收容部45a之 壁部之間，塡充黏接劑4 2成爲包圍觸控面板4的平面 視框狀。亦即，觸控面板4被固定於薄膜構件3 〇與覆 構件45雙方。 密 膜 之 爲 與 4 5 造 4 薄 於 而 力 的 置 內 俯 蓋 -50- 200903074 接著，根據在觸控面板4與覆蓋構件4 5之間被配設 黏接劑4 2的輸入裝置4 0 B，除了可以得到與先前說明的 輸入裝置40A同樣的作用效果以外，還可以得到以下的作 用效果。 首先，把觸控面板4藉由黏接劑4 2固定於覆蓋構件 45，相關於第1構成例之背面側薄膜構件3 1變成不再需 要。因此，例如於觸控面板4的背面側設置液晶面板等顯 示手段，而在透過觸控面板4進行顯示的場合，透過背面 側薄膜構件3 1時之光損失或在背面側薄膜構件3 1表面之 反射不再發生，因而可得明亮的顯示。 此外，觸控面板4在基板面方向及基板厚度方向之任 一之方向的移動都被限制住，所以可避免由於觸控面板4 的輸入操作而使觸控面板4被壓陷入深處，或者由於落下 的衝擊而使觸控面板4在收容部4 5 a內移動，可使其成爲 操作性及耐久性優異的輸入裝置。 相關於第2構成例的輸入裝置40B，可以與參照圖1 3 及圖14而說明的第1構成例之輸入裝置40A同樣地製 造。但是，在輸入裝置40B，因爲不需要背面側薄膜構件 3 1，所以只要替代黏接圖1 3 ( b )所示的背面側薄膜構件 31的步驟，而設置在配置於收容部45a內的觸控面板4與 收容部4 5 a之內壁之間’配設黏接劑4 2的步驟即可。於 此場合，黏接劑42可以在把觸控面板4收容於收容部45a 內之後藉由塗布器等塗布於特定位置’但預先將黏接劑42 塗布於收容於收容部45a內的觸控面板4的側面部亦可。 -51 - 200903074 或者是，在收容部45a的內壁面預先塗布黏接劑42亦 可。 [第3構成例] 其次，圖15係第3實施型態之輸入裝置之第3構成 例之輸入裝置40C的槪略剖面圖。圖15係相當於第1構 成例之圖1 〇 ( a )之圖。 本例之之輸入裝置40C與第2構成例之輸入裝置40B 之不同點，在於跨覆蓋構件45與觸控面板4而被形成的 薄膜構件130，具備層積第1樹脂層131、與第2樹脂層 1 43之構成這一點。亦即，於圖1 5對與圖1 0之共通的構 成要素，賦予相同符號而省略詳細說明。 如圖1 5所示，薄膜構件1 30，具備：覆蓋構件45的 主面45a與從面板支撐部45A的開口部45b露出的觸控面 板4的主面4s之平面形狀的第1樹脂層1 3 1，與被形成於 與第1樹脂層1 3 1的覆蓋構件45之相反側之面的第2樹 脂層1 3 2。 第1樹脂層131，與第1構成例及第2構成例之單層 構造的薄膜構件30同樣，可以使用PET ( polyethylene terephthalate，聚對苯二甲酸乙一醇醋）等聚乙稀、聚 酯、聚丙烯等透明樹酯材料所構成之薄膜材。 第2樹脂層1 3 2，如圖1 5所示，被配置爲部分形成於 第1樹脂層1 3 1上，成爲與遮光膜46同樣之平面俯視約 略矩形框狀而與遮光膜46平面重疊。第2樹脂層132，具 -52- 200903074 有對應於遮光膜46的開口部46a之平面俯視矩形狀 口部l32a’相關的開口部132a被形成於遮光膜46的 部46a的內側。在第2樹脂層132的開口部132a內 出下層側的第1樹脂層1 3 1。 第2樹脂層13 2，使用比構成第1樹脂層1 3 1的 材料硬度更低（柔軟性更高）的樹脂材料來形成。例 第1樹脂層1 3 1爲PET薄膜所構成的話，第2樹脂層 使用聚乙烯或聚尿烷、壓克力等來形成。 在具備前述構成之本例的輸入裝置40C，薄膜 130爲第1樹脂層131與第2樹脂層132之2層構造 關構成的薄膜構件30，在使熱溶接於觸控面板4及覆 件45時’與第1樹脂層1 3 1相比使用硬度低的樹脂 來形成的第2樹脂層1 3 2軟化而擴開，所以對於觸控 4與覆蓋構件45之邊接部的階差之薄膜構件1 30的圍 良好，可以提升與薄膜構件130及觸控面板4與覆蓋 45之密接性。藉此，可以實現可信賴性及新式樣性雙 優異的輸入裝置。 此外，於輸入裝置40C，在觸控面板4上相對高 之第1樹脂層1 3 1露出，所以成爲可良好地防止對觸 板4進行座標輸入操作時使輸入器具3或手指等滑動 上，因操作導致的磨耗或對覆蓋構件45或觸控面板 表面之刮傷等之構成。作爲第1樹脂層1 3 1，最好使 以良好地防止前述磨耗或刮傷，或者可得良好的透過 PET薄膜。 的開 開口 ，露

例的場合，只要至少設於觸控面板4與覆蓋構件45之邊 界部即可達成所期待的目的。 此外，第2樹脂層132，不限於觸控面板4與覆蓋構 件45之邊界部，亦可配置於被形成其他階差的區域。例 如，於覆蓋構件45的主面45s被形成有突起或凹部的場 合，選擇性地在俯視平面與這些突起或凹部重疊的位置上 形成第2樹脂層1 32的話，可以在被形成突起或凹部的部 位使薄膜構件1 3 0良好地密接。 此外，在本例，係針對黏接2層構造的薄膜構件1 3 0 的構成加以說明，但亦可替代薄膜構件1 3 0，而設置層積 3層以上的樹脂層之薄膜構件。藉由使用選擇性平面配置 硬度不同的複數樹脂層而成的薄膜構件，可以高度控制溶 接時之密接性（對凹凸之追隨性），可謀求提高輸入裝置 的可信賴性及新式樣性。 進而，替代薄膜構件130，而使用在平面區域內被區 隔形成硬度不同的樹脂膜的構成之薄膜構件亦可。例如， 也可以使用把對應於觸控面板4的主面4s的俯視平面爲 矩形狀的PET薄膜，與以俯視平面上包圍此PET薄膜的 方式被配置的聚乙烯薄膜，在二者相接的部分一體化的薄 膜構件。 -54 - 200903074 <第3構成例之輸入裝置之製造方法> 其次，參照圖1 6，說明相關於第3構成例之輸入裝置 40C的製造方法。圖16係顯示輸入裝置40C的構造步驟 之槪略剖面圖。圖1 6所示之剖面構成，相當於沿著圖1 1 所不之A - A ’線的位置之剖面構成。 首先，如圖16(a)所示，準備具有收容部45a與面 板支撐部45A之覆蓋構件45，把另行製作的觸控面板4， 輸入操作面之主面4 s由被形成面板支撐部4 5 A的相反側 的收容部4 5 a之開口端側起嵌入收容部4 5 a內。其後，使 例如PET薄膜所構成的背面側薄膜構件3 1跨覆蓋構件45 與觸控面板4的背面側基板8b而黏接。 此外，如圖16 ( a )所示，準備層積例如PET薄膜所 構成的第1樹脂層1 3 1，及例如聚乙烯薄膜所構成的第2 樹脂層132而成的薄膜構件130。於薄膜構件30之成爲覆 蓋構件45側的面上，被印刷遮光膜46。 接著，如圖1 6 ( b )所示，以使印刷面朝向覆蓋構件 45側的狀態，覆蓋覆蓋構件45以及觸控面板4的方式配 置薄膜構件130。此時，薄膜構件130的表面之遮光膜46 的開口部46a，以使遮光膜46的開口部46a被配置於面板 支撐部45A的開口部45b內的方式對準位置。 其次，如圖16 ( c)所示，使用加熱裝置3 50加熱薄 膜構件1 3 0，使薄膜構件1 3 0軟化，把薄膜構件1 3 0熱溶 接於觸控面板4以及覆蓋構件45。作爲這樣的溶接方法， -55- 200903074 可以使用熱板溶接、真空熱溶接、振動溶接、超音波溶 接、雷射溶接、衝擊溶接、高頻誘導加熱溶接、電磁誘導 加熱溶接、熱壓溶接等溶接方法。 如此一來，如圖1 6 ( d )所示，軟化的薄膜構件130 進入面板支撐部4 5 A的開口部4 5 b內，以沿著觸控面板4 的主面4 s、以及觸控面板4與覆蓋構件4 5之階差的方式 密接於觸控面板4與覆蓋構件4 5。此外藉由此步驟，於薄 膜構件1 3 0的表面被形成跟隨於觸控面板4與覆蓋構件4 5 之階差的形狀之階差部43。 在本實施型態，因爲在薄膜構件130的第1樹脂層 1 3 1上被形成由硬度低的樹脂材料所構成的第2樹脂層 1 3 2，所以藉由加熱裝置3 5 0的加熱，柔軟性很高的第2 樹脂層1 3 2在第1樹脂層1 3 1上擴展開。藉此，成爲薄膜 構件130圓滑地密接於觸控面板4與覆蓋構件45之階 差。 如以上所說明的，根據本實施型態之製造方法，因爲 熱溶接2層構造的薄膜構件130使對觸控面板4、以及對 觸控面板4與覆蓋構件45之階差密接，所以對於觸控面 板4與覆蓋構件45之階差可以對觸控面板4與覆蓋構件 45之階差圓滑地使薄膜構件1 30密接。因而，有效果地緩 和前述階差，可以簡便的步驟製造提高設計自由度之輸入 裝置40C 。 此外，在被設於覆蓋構件4 5的收容部4 5 a使面板4 嵌入，進而因爲由觸控面板4的背面側黏接固定背面側薄 -56- 200903074 膜構件3 1，所以可以極爲簡便的步驟將觸控面板4固定於 覆蓋構件45。 [第4及第5構成例] 其次，圖17(a)係第3實施型態之輸入裝置之第4 構成例之輸入裝置40D的槪略剖面圖。圖1 7 ( b )同樣係 第5實施型態之輸入裝置40E的槪略剖面圖。圖1 7 ( a ) 及圖17(b)係相當於第1構成例之圖10(a)之圖。 第4構成例之輸入裝置40D係以第1構成例之輸入裝 置4 0A爲基本構成，在跨覆蓋構件45與觸控面板4而被 形成的薄膜構件3 0被形成開口部3 0 a這一點有所不同。 此外，第5構成例之輸入裝置40E係以第3構成例之 輸入裝置40C爲基本構成，在跨覆蓋構件45與觸控面板 4而被形成的薄膜構件1 3 0被形成開口部1 3 0a這一點有所 不同。 亦即，於圖1 7對圖10及圖15之共通的構成要素， 賦予相同符號而省略詳細說明。 如圖17(a)所示，相關於第4構成例之輸入裝置 4〇D之薄膜構件30的開口部30a，係沿著以重疊於觸控面 板4的周緣部被形成的遮光膜46的開口部46a的端緣被 形成爲矩形狀，對應於成爲觸控面板4的輸入操作部的平 面區域而開口。 此外，如圖1 7 ( b )所示，相關於第5構成例之輸入 裝置40E之薄膜構件130的開口部130a，也係沿著以重 -57- 200903074 疊於觸控面板4的周緣部被形成的遮光膜46的開口部46a 的端緣被形成爲矩形狀，對應於成爲觸控面板4的輸入操 作部的平面區域而開口。 亦即，在輸入裝置40D、40E ’在前面側基板8a上使 直接輸入器具3或者手指滑動’而進行對觸控面板4之輸 入操作。 具備前述構成之第4及第5構成例之輸入裝置4〇D、 4 0 E因爲將前面側基板直接按壓而進行對觸控面板4之輸 入操作，所以與透過薄膜構件3 0進行輸入操作的第1構 成例之輸入裝置40A，以及透過薄膜構件130進行輸入操 作之第3構成例之輸入裝置40C相比操作壓力變低，可以 進行適切的輸入操作。 又，在第4及第5構成例，部分除去薄膜構件30以 及薄膜構件130而形成開口部30a、130a，所以薄膜構件 30或者薄膜構件130與觸控面板4被黏接的區域僅爲觸控 面板4(前面側基板8a)之周緣區域而已。此周緣區域之 寬幅，雖隨觸控面板4之尺寸而不同，但通常至少可以確 保數mm程度，所以可以確保薄膜構件3 0或者薄膜構件 130與觸控面板4之黏接強度。 但是，比較先前的構成例之輸入裝置40 A、40C的 話，黏接面積狹窄且黏接強度變低，所以於第4及第5構 成例之輸入裝置40D、40E，與相關於第2構成例之輸入 裝置40B同樣，於觸控面板4與覆蓋構件45之間隙配設 黏接劑42而黏接覆蓋構件45與觸控面板4爲較佳。 -58- 200903074 此外，第4及第5構成例之場合，如圖1 7所示，被 形成於薄膜構件3 0或者薄膜構件1 3 0之覆蓋構件4 5側之 遮光膜46，分別形成於薄膜構件30的開口部30a的外 側，及薄膜構件1 3 0的開口部1 3 0a之外側，且以遮光膜 46的端緣不露出於開口部30a、130a內者較佳。藉由如此 般構成，可以防止由遮光膜46與薄膜構件30、130之界 面產生剝離，此外可以有效果地保護遮光膜46。 進而，在第4及第5構成例，因爲是觸控面板4之前 面側基板8 a露出的構造，所以前面側基板8 a的基板本體 1 1 a如果是玻璃基板的話，會有由於落下等之衝擊而使玻 璃基板破損時破片會四處飛散之虞。亦即，採用如本例所 示之構成的場合，作爲前面側基板8a之基板本體11a最 好是使用高強度之玻璃基板或塑膠基板。或者是，在基板 本體11a的表面塗布透明樹脂等形成保護層較佳。 [第4實施形態] 其次，參照圖1 8說明本發明之第4實施型態之光電 裝置。 圖1 8係顯示相關於第4實施型態之光電裝置之一例 之觸控面板一體型之液晶裝置之槪略剖面圖。 如圖1 8所示之液晶裝置1 00A，被構成爲具備：顯示 部之液晶面板（光電面板）2，被配設於其前面側（圖示 上側；觀察側）之第3實施型態的輸入裝置40A。 輸入裝置40A，如前所述，具備：類比型電阻膜方式 -59- 200903074 之觸控面板（輸入面板）4，具備收容觸控面板4的收容 部45a之覆蓋構件45，覆蓋觸控面板4及覆蓋構件45而 與覆蓋構件45的主面45s與觸控面板4的主面4s黏接之 薄膜構件3 0，以及被黏接於觸控面板4的背面側之背面側 薄膜構件3 1。 液晶面板2，藉由包含透光性的彈性體（例如，與玻 璃之折射率差比空氣還要小的矽凝膠、壓克力凝膠、氨基 甲酸乙酯凝膠、氨基甲酸乙酯橡膠等透光性之彈性體）的 黏接劑5 0，與被黏接於觸控面板4的背面側的背面側薄膜 構件3 1光學黏接。以藉由彈性體構成黏接劑5 0，使彈性 體吸收對觸控面板4進行輸入操作時之按壓力，可以抑制 由於輸入操作所導致液晶面板2的基板因應變（strain ) 而導致顯示不良。 液晶面板2、偏光板以及照明裝置（背光）的構成如 在第2實施型態所說明的。 根據具備以上的構成之本例的液晶裝置1 00A，因爲 具備第3實施型態之輸入裝置40A、與輸入裝置40A之背 面側薄膜構件3 1黏接之液晶面板2，所以可進行透過觸控 面板4的顯示。 接著，在本實施型態之液晶裝置，藉由被黏接於顯示 面側的薄膜構件3 0，觸控面板4與覆蓋構件4 5之間的階 差變成平滑連續的形狀，此外在薄膜構件3 0可以施以任 意的印刷，所以設計上的自由度很高，成爲可得到優異的 新式樣性之液晶裝置。 -60- 200903074 此外在本實施型態之液晶裝置’於觸控面板4的前面 側被配設薄膜構件3 0，所以可以安全地使用在前面側基板 8 a用了玻璃基板的觸控面板4。於2枚基板本體11 a、1 1 b 之雙方使用玻璃基板之觸控面板’與基板本體11a爲塑膠 基板者，或者與基板本體"a、lib雙方均爲塑膠基板者 相比可得高透過率，所以與從前相比可得到明亮且高畫質 的顯示。 又，在本實施型態針對組合液晶面板2與輸入裝置 4 0 A之構成的液晶裝置加以說明，但亦可組合液晶面板2 與輸入裝置40B〜40E之任一。此外，替代液晶面板2， 配置有機EL面板等其他顯示手段亦可。 (電子機器） 其次，參照圖19、20及圖2 1，說明相關於本發明之 電子機器。 圖19(a)、圖20(a)係具備先前的實施型態之液 晶裝置的

)所示，具 備：以構成PDA200的顯示部兼操作部的方式被加工爲特 -61 - 200903074 定形狀之覆蓋構件45、被支撐於覆蓋構件45的觸控面板 4、與被配設於觸控面板4的背面側之液晶面板2。此外， 於觸控面板4以及覆蓋構件45的表面被黏接省略圖示的 薄膜（3 0 )，保護觸控面板4的輸入操作面以及覆蓋構件 45的表面。 於覆蓋構件45，設有複數之貫通孔45c，於這些貫通 孔45c插入功能鍵202而使露出於表面側。此外，於貫通 孔45c的附件，在覆蓋住覆蓋構件45的薄膜的背面側 (覆蓋構件45側）被配置有印刷的識別資訊（文字或圖 形）。 本實施型態之PDA200，係藉由一面看著被印刷於功 能鍵2 0 2附近的識別資訊，或被配置於觸控面板4之下的 液晶面板2的畫面顯示，同時直接指示觸控面板4上的位 置，而進行資料輸入等操作。 此處，圖21係供比較而顯示之從前構成的PDA。圖 21所示之PDA1000，具備筐體1001，功能鍵1002，以及 被配置於筐體1001的開口部之觸控面板1004。於觸控面 板1 004之下被配設省略圖示之液晶面板。 如圖所示，從前係將觸控面板1 004以被形成於筐體 1001的框（frame)部1003按壓而支撐的構造，所以觸控 面板1 〇 〇 4之操作面與框部1 0 0 3之間被形成有階差部 1003a。接著，因爲此階差部1003a的緣故，觸控面板 1 0 04之操作面與其周圍之框部1 003之間被明顯地區隔， 使得筐體1 〇〇 1的設計受到限制。 -62- 200903074 對此’根據具備前述構成知本實施型態之PDA200的 話’作爲輸入裝置兼作顯示裝置而具備前述之本發明的液 晶裝置’所以觸控面板4與其周圍的覆蓋構件4 5之間沒 有階差’或者是階差藉由薄膜構件而成爲平滑連續的形

Description of the Invention [Technical Field of the Invention] The present invention relates to an input device, an optoelectronic device, and an electronic device. [Prior Art] In recent years, with the spread of small information electronic devices such as personal digital assistants (PDAs) and palm-sized computers, liquid crystal devices equipped with touch panels as input devices on liquid crystal panels have been widely used (for example, Patent Document 1). [Patent Document 1] Japanese Patent Laid-Open Publication No. 2003- 4345 No. 2003-A. [Problems to be Solved by the Invention] However, when a liquid crystal device including a touch panel is used as a display portion of an electronic device, it is necessary to make Since the touch panel is exposed on the surface of the casing, the frame edge portion of the touch panel is usually pressed by the casing. In such a structure, a step is formed between the casing and the operation surface of the touch panel (see Fig. 20), and the design integrated with the casing cannot be adopted, so that the degree of freedom in design is low. The present invention has been made in view of the above-described problems of the prior art, and it is an object of the invention to provide a new type of electronic device having an input means, and more preferably an input device and an optoelectronic device which can improve reliability. [Means for Solving the Problems] -4-200903074 In order to solve the above problems, the input device of the present invention includes an input panel, a cover member provided with an accommodating portion for accommodating the input panel, and a straddle disposed therebetween. A flexible (thin film) member in which one of the main faces of the input panel and the main surface of the cover member is adhered to each other. According to this configuration, since the flexible member is bonded to the cover member and the cover member in a state in which the input panel is housed in the accommodating portion of the cover member, the input panel and the cover member which are damaging the design of the past can be eliminated. The step difference of the boundary. Thereby, an input device excellent in new style can be realized. Further, since the flexible member is disposed on the main surface side of the input panel, when the input panel has a glass substrate, the breakage of the fragments can be prevented even if the glass is broken. Further, with the elimination of the step, it is possible to eliminate the accumulation of dust in the step portion or the fact that the water droplets are infiltrated by the boundary between the input panel and the covering member, and an input device excellent in reliability can be realized. Alternatively, the second flexible member may be bonded to the side opposite to the input panel with the flexible member. According to this configuration, since the movement of the input panel in the thickness direction of the panel is restricted by the second flexible member, it is possible to prevent the input panel from being pressed by the pressing force of the input device or the finger when the input operation is performed on the input panel. Press into the deep side. The aforementioned flexible member is preferably a film member. When a thin film member is used for the flexible member, it is possible to prevent an increase in the operating pressure on the input panel, and it is possible to obtain a high-quality image by performing a high-intensity -5 - 200903074 transmittance when the liquid crystal panel or the like is displayed through the input panel. The display. Further, a film member can be used for the second erasable member, and it is possible to prevent the entire input device from becoming thick, which is an input device that can constitute a thin electronic device. It is also possible to adopt a configuration in which a light shielding film is formed on the surface of the film member on the side of the input panel. Since the light shielding film is formed on the film member in this manner, it is possible to easily form a shadow of an unnecessary portion. Further, the alignment of the light shielding film can be easily performed. Further, the design can be improved. Preferably, the film member and the input panel are optically bonded. According to this configuration, when the display is transmitted through the input panel, it is possible to prevent unnecessary reflection at the interface of the air layer between the input panel and the film member, and it is possible to prevent a deterioration in display quality and a bright display. The film member may be configured to have an opening in a planar area of the input panel. By providing the opening portion ' in the film member as described above, the operation surface of the input panel can be exposed', and the operation pressure can be reduced to easily perform the input operation. According to the present invention, since the input member and the covering member are bonded to the thin member, a large step is not formed in the opening portion of the film member, and the operability can be improved without impairing the new pattern. It is also possible to adopt a configuration in which an adhesive is disposed between the input panel and the inner wall surface of the housing portion. According to this configuration, since the cover member and the input panel are bonded to each other, the input panel can be more stably supported, and the input panel can be more reliably prevented from being pressed and depressed during the input operation. The aforementioned flexible member -6 - 200903074 member to be bonded to the one main surface side of the input panel may be a polarizing plate. With such a configuration, the optical element such as a part of the display means such as the liquid crystal panel disposed on the back side of the input panel can be disposed on the front side of the input device. The front side of the input panel is not limited to a polarizing plate, and other optical components may be disposed. For example, an optical element in which a laminated polarizing plate and a phase difference plate are disposed may be provided with an antireflection film or a light diffusion film. Preferably, the accommodating portion is an opening portion formed to penetrate the covering member. According to such a configuration, processing for forming the accommodating portion becomes easy, and the input device can be manufactured at low cost. In the present invention, since the input panel disposed in the accommodating portion is supported by the flexible member that is bonded to the main surface of the cover member across the main surface of the input member, the accommodating portion itself does not need to have a function of holding the input panel. In addition, the influence of the unevenness of the size (especially the thickness) of the input panel can be eliminated. According to a second aspect of the invention, a photovoltaic device includes: an input panel; a cover member provided with an accommodating portion for accommodating the input panel; and a main surface of the input panel disposed between the accommodating portion and the front surface An input device for a flexible member to which one of the cover members is bonded, and a photovoltaic panel disposed on a side opposite to the flexible member of the input device. According to this configuration, an excellent new style can be obtained by the input device according to the present invention, and an optoelectronic device capable of performing an input operation and image display through the input panel can be provided. -7- 200903074 As the photovoltaic panel, various display devices such as a liquid crystal panel, an organic EL panel, and an electrophoretic display panel can be used. Alternatively, a plasma display device or a field emission display device (Field Emission Display: FED) may be used, and the substrate constituting the photovoltaic panel and the surface of the input device opposite to the flexible member may be the most It is well bonded by optics. According to this configuration, it is possible to prevent the display light emitted from the photoelectric panel from being reflected by the substrate surface of the input panel constituting the input device, and to obtain a bright display. The photovoltaic panel may be fixed to the cover member so as to be configured to hold the input panel between the flexible member and the flexible member. Thus, by sandwiching the input panel between the photovoltaic panel and the flexible member, the movement of the input panel in the thickness direction of the panel is restricted, so that the input panel can be prevented from being pressed into the photovoltaic panel side during the input operation of the input panel. The aforementioned flexible member may be a polarizing plate. According to this configuration, since the polarizing plate disposed between the photovoltaic panel and the input device is disposed outside the input panel, the space on the back side of the input panel can be saved, and the electronic device can be easily mounted on a small electronic device. Optoelectronic device. A light-transmitting elastic member may be disposed between the substrate constituting the photovoltaic panel and the surface of the input device on the side opposite to the flexible member. The input device of the present invention has a cover panel, a cover member provided with an accommodating portion for accommodating the input panel, and an input panel that is accommodated in the accommodating portion, as another aspect of the present invention. a main surface is bonded to one of the main surfaces of the cover member, and is closely adhered to the step of the boundary between the main surface of the input panel and the main surface of the cover member along -8-200903074. The input panel and the film member of the cover member. According to this configuration, the film member is deformed and adhered in accordance with the step formed on the boundary between the main surface of the input panel and the main surface of the cover member. Therefore, the surface of the film member is relaxed and the surface is smooth and continuous. The shape 'can prevent a design degradation due to the step difference. Thereby, an input device excellent in new style can be realized. Further, since the film member is disposed on the main surface side of the input panel, and the input panel has a glass substrate, even if the glass is broken, the fragments can be prevented from scattering. Further, since the film member is adhered by covering the step of the boundary portion, it is possible to eliminate the accumulation of dust in the step portion or the water droplets are infiltrated by the boundary between the input panel and the covering member, and an input device excellent in reliability can be realized. The back surface of the input panel may be adhered to the back surface of the input panel together with the film member on the back surface of the cover member and the back surface on the opposite side. According to this configuration, since the movement of the input panel in the thickness direction of the panel is restricted by the back side film member, it is possible to prevent the input panel from being pressed by the pressing force of the input device or the finger when the input panel is subjected to the input operation. Deep side. The film member may have an opening portion in a plane region of the main surface of the input panel. ~ 9 - 200903074 By providing an opening in the film member in this way, the operation surface of the input panel can be exposed, and the input operation can be easily performed by reducing the operating pressure. In the present invention, since the film member is bonded to the input panel and the covering member, a large step is not formed in the opening portion of the film member, and the operability can be improved without impairing the new pattern. The film member may have a structure in which a first resin layer is laminated and a second resin layer composed of a resin material having a lower hardness than the first resin layer. According to this configuration, since the second resin layer having high flexibility is provided, the film member can be flexibly deformed at the boundary between the input panel and the covering member, and the film member can be brought into close contact with the input panel and the covering member. The second resin layer member may have an opening in a planar region of the input panel. With such a configuration, since the harder first resin layer is disposed on the input panel, it is possible to satisfactorily prevent abrasion or scratches due to the input operation. Preferably, the accommodating portion of the covering member is formed with a panel supporting portion that is in contact with the input panel to support the input panel. In the case of the configuration, the panel support portion can restrict the movement of the thickness direction of the panel of the input panel, so that the alignment of the input panel of the cover member becomes easy, and the adhesion of the film member can be easily performed. Preferably, the panel supporting portion is formed in a frame shape projecting from the inner wall of the accommodating portion toward the inside of the accommodating portion. That is, the panel supporting portion is preferably configured to be pressed against the peripheral portion of the input panel. According to such a configuration, the peripheral portion of the input panel can be formed by the panel supporting portion. Further, by providing a panel supporting portion different from the accommodating portion by another -10-200903074, the height of the step of the boundary portion between the covering member and the input panel can be reduced. It is also possible to adopt a configuration in which an adhesive is disposed between the input panel and the covering member. According to this configuration, the cover member can support the input panel more stably, and the ease of the operation of the manufacturing steps, the reliability at the time of input operation, and the like can be improved. Next, a method of manufacturing an input device according to the present invention is a method of manufacturing an input device including an input panel and a cover member for supporting the input panel, and is characterized in that it is formed in a concave portion or an opening portion formed in the cover member. The accommodating portion is provided with a panel arranging step of the input panel, and a film arranging step of arranging the film member across the input surface of the input panel and the main surface of the cover member on the input operation surface side, and heating the film member to soften the film member. Adhering to the bonding step of the input panel and the cover member. According to such a manufacturing method, the film member can be adhered to the input panel and the covering member extremely easily, and the film member can be easily deformed to have a shape in accordance with the boundary portion. In the bonding step, the film member is preferably bonded by vacuum heat sealing. According to this manufacturing method, the bonding and adhesion of the film member can be performed extremely easily and efficiently. Further, a step of adhering the back side film member supported by the back surface side to the back surface of the covering member on the main surface and the opposite side may be provided. With such a manufacturing method, the input panel can be fixed to the covering member before the film member is bonded, and the film member can be bonded correctly, and -11 - 200903074 is a manufacturing method that contributes to productivity improvement. The film member may have a second structure in which a first resin layer is laminated and a resin material having a lower hardness of the resin layer is formed. In the film arrangement step, the second resin may be disposed at a boundary portion of the input cover member. Floor. . In the root method, since the second resin layer having higher flexibility is disposed, it is easy to deform the film member depending on the shape. According to the present invention, the input device of the present invention is characterized in that the accommodating portion that is provided in the panel and that houses the input panel is bonded to the main surface of one of the main members of the input panel that is housed in the accommodating portion, and is bonded thereto. The film is adhered to the film of the input panel and the cover member along a boundary between the main surface formed on the front surface and the main surface of the cover member, and is disposed on the film-forming photovoltaic panel of the input device. According to this configuration, the photoelectric device capable of performing the input operation and the transparent image display can be provided by the new style of the input device according to the present invention. As the photovoltaic panel, various types of display devices such as a liquid crystal panel or a plate and an electrophoretic display panel can be used.

According to this configuration, it is possible to provide a new pattern and a member of the first resin layer and the boundary portion of the manufacturing cover having the step of the cover member and the surface and the cover member. The input side of the input part is excellent. The organic EL surface of the input panel can be used. The electric device can be used: Field input device, excellent electric -12-200903074 sub-machine. [Embodiment] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, in the drawings referred to below, the ratio of the film thickness or the size of each constituent element is appropriately changed for easy identification. [First Embodiment] Fig. 1 (a) is a schematic cross-sectional view of an input device 40 A according to a first configuration example of a first embodiment of the present invention. Fig. 1 (b) is also a schematic cross-sectional view of the input device 40B relating to the second configuration example. Figure 2 is a schematic plan view of the input device 40A shown in Figure 1. 3 is an exploded perspective view showing the configuration of the touch panel 4. [First configuration example] As shown in Fig. 1 and Fig. 2, the input device 40A of the present embodiment includes a cover member 45 having a substantially planar shape in plan view, and is disposed in a rectangular shape formed in the cover member 45. The touch panel (input panel) 4 of the analog type resistive film type in the accommodating portion 45a formed by the opening portion, and the main surface 45s (the front surface side of FIG. 2) of the cover member 45 and the touch panel 4 The film member (flexible member) 30 whose main surface is bonded for 4 s. On the side of the covering member 45 of the film member 30, a light-shielding film 46' formed by printing, for example, has a rectangular opening 46a in a planar region corresponding to the input portion 40a of the touch panel 4. In other words, the plane of the touch panel 4 -13 - 200903074 is a planar region other than the entrance portion 40a (a planar region from the outside of the input portion 40a until the end portion of the substrate body lib) is shielded by the light shielding film 46. The thickness of the touch panel 4 is almost the same as the thickness of the cover member 45, and is set such that the thickness of the touch panel 4 is within the thickness of the cover member 45. That is, the touch panel 4 is housed in the accommodating portion 45a of the cover member 45, and the main surface 4s of the touch panel 4 and the main surface 45s of the cover member 45 are disposed at almost horizontal positions in a side cross-sectional view. An adhesive agent (not shown) is provided between the main surface 45s of the cover member 45 and the film member 30 (light-shielding film 46), and the touch panel 4 of the main surface 4s of the touch panel 4 and the film member 30 is further provided. On the side surface, the adhesive member 41, which is provided with optical bonding, adheres to the film member 30 and the covering member 45, the touch panel 4 and the film member 30, respectively. As a result, as shown in Fig. 1(a), the surface of the film member 30 supporting the touch panel 4 and the covering member 45 becomes a flat surface having no step. In short, there is a configuration in which substantially no step difference occurs between the main surface 4s of the touch panel 4 and the main surface 45s of the cover member 45. The touch panel 4' has a front side substrate (first substrate) 8a and a back side substrate which are opposed to each other by a predetermined gap in the peripheral portion of the two substrates 8a and 8b. 2 substrate) 8b bonding integration. As shown in FIG. 3, the front side substrate 8a of the touch panel 4 is formed on the inner surface (the surface on the back side substrate side) of the substrate body 11a of the transparent substrate, and is formed of a transparent conductive material. Planar-shaped planar electrode-14-200903074 (high-resistance film; first electrode) 12a, both ends of the planar electrode 12a in the Υ direction (the opposite ends of the rectangular planar electrode 12a) A pair of low resistance films 13 are formed. The low-resistance film 13 formed on the front side substrate 8a is electrically connected to the auxiliary electrode 18 formed on the back side substrate 8b through the conductive material 17, and is further pulled out to the terminal portion 16 through the auxiliary electrode 18. . The low-resistance films 13 and 14 and the auxiliary electrode 18 constitute a wiring portion of the touch panel 4, and are formed along the peripheral portion of the substrate 8a or the substrate 8b. On the other hand, the back side substrate 8 b of the touch panel 4 is formed on the inner surface (surface on the front substrate side) of the substrate body 1 1 b of the transparent substrate, and is formed of a transparent conductive material. A planar electrode (high-resistance film; second electrode) 12b having a planar shape is formed at both end portions in the X direction (the opposite end portions of the rectangular planar electrode 12b) of the planar electrode 12b. The composition of the low resistance film 14 is obtained. A terminal portion 16 connected to the wiring drawn from the low-resistance film 13 and the low-resistance film 14 is formed at the edge end portion of the back side substrate 8b. As shown in FIG. 1, the flexible printed circuit board is connected to the terminal portion 16 through an ACP (Anisotropic Conductive Paste) or an ACF (Anisotropic Conductive Film) to connect the terminal portion 16 to the outside. The control circuit is electrically connected. In the present embodiment, the outer side surface of the front side substrate 8 a and the planar area corresponding to the formation area of the planar electrode 12 a are coordinate input surfaces (the position on the touch panel is directly indicated by the input device 3 or a finger or the like). The aforementioned input portion 40a) of the operation surface of the operation is input. -15- 200903074 A hard glass substrate is used for each of the substrates 1 1 a and 1 1 b constituting the front side substrate 8a and the back side substrate 8b. By making the front side base a glass substrate, there is no problem that the substrate or the electrode is deteriorated as in the case where the plastic substrate is used for the front side substrate. On the other hand, the glass substrate lacks flexibility compared to the plastic film substrate. Therefore, if the applied load is too small, the input may not be sufficiently input. In this embodiment, the thickness of the glass substrate is reduced. To 〇. 11 0. The problem of operability is solved by the degree of 2 m m. On the other hand, the substrate main body 1 1 b as the constitution side substrate 8 b is the same as the liquid crystal panel or the like. For example, in this example, the back side substrate 8 of the touch panel 4 is made 0. 5mm level. The planar electrodes 12a and 12b are made of a conductive film such as ITO (Indium Tin Oxide), and have almost uniform resistance in the entire area in the plane. Further, the low-resistance films 13 and 14, the auxiliary electrode 18 and the terminal 16 are made of a highly conductive metal thin film such as Au, Ag, Cu, Cr, or an alloy containing any one or more of these metals. to make. In the present embodiment, since the glass substrate is used as the substrate body of the front side substrate 8a and the back side 8b, unlike the conventional touch panel, the high temperature heat treatment or the etching treatment using a strong etching solution can be performed. Therefore, in the present embodiment, the conductive films (the planar electrodes 12a, i2b, the auxiliary 18, the terminal portion 16, and the like) for detecting information are formed by using a vacuum such as a sputtering method or a vapor deposition method, and further The fields of the low-resistance films 13 and 14 and the body plate 8 a are hard-timed by the etching process. The thick surface of the surface of the substrate is made of ήm~, and the acidity of the substrate is made. -16- 200903074 Electrode 1 8 is thinned to form a wiring portion with a narrow frame edge. For example, when APC (AgPdCu alloy, specific resistance is about 4xl〇-6Qcm) is used in the wiring portion, the pull-back wiring '20 mm thick and 1 mm line width made from silver paste before can be made into a thickness of 0 in APC. . 2 μ m, line width 0 _ 1 m m. In addition, the specific resistance (Dcm) of copper, aluminum, and chromium is 6χ10·6, 6χ1 (Γ6, 5×10_5, respectively), so even if these metals are used, the line width can be narrower than before. 1 to 2 orders of magnitude. The buffer member 15 made of a resin material or the like is arranged on the planar electrode 1 2 b of the back side substrate 8 b. The buffer member is preferably made of an elastic material such as enamel resin or urethane. (for example, the elastic modulus is in the range of 1 X 1 〇 4 N/m 2 to 1 x 10 8 N/m 2 ), and is formed on the planar electrode 1 2 b by photolithography or printing. This buffer structure also serves as the control substrate 8 a, A spacer for the gap of 8 b functions. As the film member 30 bonded to the touch panel 4, polyethylene such as PET (polyethylene terephthalate) or the like can be used. A film material composed of a transparent resin material such as an ester or a polypropylene. When the input device 40A performs a coordinate input operation on the touch panel 4, the input device 3 or a finger or the like slides on the surface of the film member 30, or is also touched. The back side of the panel 4 (film member 30 The opposite side is used as a display device with a display device such as a liquid crystal panel. Therefore, as the film member 30, it is preferable to prevent wear due to the operation or damage to the surface of the cover member 45 or the touch panel 4 as well. In addition, it is preferable that a good transmittance can be obtained. As the adhesive -17-200903074 (adhesive) provided between the film member 30 and the touch panel 4, an acrylic system, a rubber system, or the like can be used. Various kinds of adhesives such as eucalyptus ester. In the present embodiment, since the optical adhesive film member 30 and the touch panel 4 are used, it is preferable to use an eucalyptus-based adhesive. The film is formed on the film member 30. The light shielding film 46 on the side of the member 45 is, for example, a colored film formed by applying a black material or a white material by printing. In the case of the present embodiment, the region of the sealing material 9 of the touch panel 4 is formed, or The portion in which the terminal portion 16 is formed functions as a shield, and when a display means such as a liquid crystal panel is provided on the back side of the touch panel 4 (opposite side of the film member 30), it is also shielded from the periphery of the display. The light-shielding film 46 may have any light-shielding property as long as it has a light-shielding property, and may be provided with a pattern. In the film member 30, not only the light-shielding film 46 but also a color and a pattern may be applied. The related design may be formed on either side of the film member 30, but it is preferably formed on the side of the covering member 45 from the viewpoint of protecting the printed matter. The covering member 45 is composed of a plastic plate or a metal plate. There is no particular requirement as long as it is a substrate having a specific strength. The cover member 45 is used not only as a support for the touch panel 4 but also as a member constituting an operation panel of an electronic device. In this case, it can be used as an operation unit built in the touch panel. Further, when the input device 40A is used as the operation unit of the electronic device, the operation button or the through hole for the switch can be provided in the cover member 45, and such processing can be easily achieved by punching or cutting. Further, printing can be performed on the film member 30, so that text information such as a description of a button or a switch can be printed. -18- 200903074 The input device 4A' of the present embodiment having the above-described configuration is provided with a touch panel 4' disposed across the main surface 4s of the touch panel 4 in the accommodating portion 45& The configuration of the main surface 45s of the covering member 45 and the adhesion of the film member 30 "eliminates the step difference between the input operation surface of the touch panel 4 and the surface of the cover member 45 on the outer side. By this, the degree of freedom in design can be improved as compared with the previous one, and it becomes an input device which can obtain excellent new style. In addition, in the case where there is a step between the touch panel and the casing as before, there is a problem that water droplets are immersed in the casing from the gap of the step portion when the step is accumulated or the water droplets adhere to it. In the present embodiment, since the entire cover member 45 is covered with the film member 30, there is no possibility of accumulation of dust and the appearance of the dust, or the infiltration of water droplets causes a failure or the like, and the input device is excellent in reliability. In addition, in thickness 〇. 1 ~ 〇. The front side substrate 8 a of the touch panel 4 formed of the thin glass substrate of 2 mm is attached to the film member 30 through the adhesive 4 1 , so that the front side substrate 8 a is broken even by the impact of falling or foreign matter. In this case, it is also possible to prevent the scattering of the glass fragments by the film member 30, and it is possible to realize an input device excellent in safety. In particular, in the present embodiment, since the film member 30 is adhered so as to cover the surface including the touch panel 4 and the covering member 45, the film member 30 is extremely difficult to peel off, which also provides excellent safety. Further, in the input device 40A of the present embodiment, the touch panel 4 is disposed in the accommodating portion 45a provided to pass through the cover member 45. That is, the covering member 45 does not restrict the movement of the substrate thickness direction of the touch panel 4 by -19-200903074. That is, even if a manufacturing difference occurs in the thickness of the touch panel 4, the touch panel 4 and the covering member 45 may be adhered to the film member 30 such that the surface of the film member 30 is flat. Here, the input operation of the touch panel 4 will be described. In the touch panel 4, an input control circuit (not shown) is connected to the terminal portion 16. The input control circuit is located at both ends of the back side substrate 8b in the X direction at a certain point of time. A specific voltage is applied between the low-resistance films 14 and 14 to electrically connect the voltages in the input control circuit between the low-resistance films 13 and 13 located at both ends of the front substrate 8 a in the Y direction. Means (voltage measuring circuit or voltage measuring element, illustration is omitted). At this point of time, the planar electrode 1 2b of the back side substrate 8b has a uniform voltage drop which causes a linearly varying voltage in the X direction, and constitutes a voltage distribution in which the X-direction portions equal to the position coordinate axis are almost at the same potential. When a certain portion of the coordinate input surface of the front substrate 8a is pressed by the tip end of the input device 3, the planar electrode 12a of the front substrate 3a and the planar electrode 12b of the back substrate 8b are in contact with each other, and the front substrate 8a is passed through the front substrate 8a. The voltage of the planar electrode 12b at the position corresponding to the portion where the input device 3 is pressed by the planar electrode 12a is measured by an input control circuit. Since the measurement is performed in relation to the position coordinate in the X direction of the pressed portion, the input control circuit can detect the position in the X direction of the portion pressed by the input device 3. On the other hand, at some other time point, a specific voltage is applied between the low-resistance films 13 and 13 located at both end portions of the front side substrate 8a in the Y direction by the input control circuit, and is located on the back side. The low-resistance film 14 and 14 at both ends of the Y-direction -20-200903074 of the side substrate 8b are in a state in which the voltage measuring means is connected. At this point of time, the planar electrode 12a of the front side substrate 8a generates a uniform voltage drop along the Y direction to form a voltage distribution in which the linear voltage changes. The input control circuit detects the voltage of the planar electrode 1 2 a of the front side substrate 8 a corresponding to the position of the portion pressed by the input device 3 by the planar electrode 12 b of the back side substrate 8 b, and Similarly to the above-described position in the X direction, the position of the pressed portion in the Y direction can be detected. By switching the two connection states of the input control circuit repeatedly in a short time, the input control circuit can detect the position coordinate X in the X direction and the position coordinate in the Y direction of the portion pressed by the input device 3 . Further, since the touch panel 4 of the present embodiment has a structure in which two glass substrates are bonded and integrated by a sealing material, it can be basically manufactured by the same method as the production of the liquid crystal panel. Therefore, as the substrate body used for the manufacture of the touch panel 4, the production line of the touch panel 4 and the production line for manufacturing the liquid crystal panel can be made common by using approximately the same thickness as the two substrates of the liquid crystal panel. However, in order to perform the coordinate input operation for the front side substrate 8a, it is necessary to provide flexibility for thinning, so that it is suitable for bonding. After two substrates having a thickness of about 5 mm, one of the substrates is subjected to an etching treatment to be thinned to 0. 1mm~0. 2mm level can be. When a thinned substrate is used from the beginning of the manufacturing process, the operation of the substrate is not easy. Depending on the occurrence of cracking of the substrate in the manufacturing step, the resistance to mechanical shock is also poor. As described above, only the substrate body 11a on the front side -21 - 200903074 is thinned after being bonded through the sealing member 9, and the occurrence of a problem in such a manufacturing step can be effectively prevented. [Second Configuration Example] On the other hand, in the input device 40B shown in FIG. 1(b), in addition to the adhesive 4 1 between the touch panel 4 and the film member 30, the touch panel 4 is The adhesive agent 42 is formed in a frame shape surrounding the touch panel 4 between the inner wall portions of the accommodating portion 45a of the cover member 45. That is, the touch panel 4 is fixed to both the film member 30 and the cover member 45. Then, according to the input device 40B in which the adhesive 42 is disposed between the touch panel 4 and the cover member 45, in addition to the same effects as those of the input device 40A described above, the following can be obtained. Effect. That is, the movement of the touch panel 4 in the direction of either the substrate surface direction and the substrate thickness direction of the cover member 45 is restricted, so that the touch panel 4 can be prevented from being touched by the input operation of the touch panel 4. It is possible to make the touch panel 4 move in the accommodating portion 455 a due to the impact of falling, or to make it into an input device excellent in operability and durability. [Third configuration example] Next, Fig. 4(a) is a schematic cross-sectional view showing an input device 40C of a third configuration example of the input device of the third embodiment. Fig. 4 (b) is a view showing the plane configuration of the input device 40C. Figure 4 (a) corresponds to Figure 1-22-200903074 (a) and Figure 1 (b), Figure 4 (b) corresponds to Figure 2 Figure 2 of the input device 40 C and the second composition The difference between the input devices of the example is that the cover member 45 and the touch panel 4 are different in that the film member 30 is formed with the opening portion 30a. The constituent elements common to those in Fig. 1 will be described in detail with reference to Fig. 4. As shown in FIG. 4, the opening portion 30a of the film member 30 is formed in a rectangular shape along the end edge of the opening 咅| of the light shielding film 46 formed on the peripheral edge portion of the touch panel 4. The opening of the flat portion of the input portion of the touch panel 4 is opened. That is, in the input device 40C, the direct input device 3 or the finger is slid on the side substrate 8a, and the input operation of the touch panel 4 is performed. Since the input device 40C of the present embodiment having the above-described configuration directly presses the front panel and performs an input operation to the touch panel 4, the input device 40A and 40B of the first embodiment in which the film member 30 performs the input operation is compared. The operating pressure is low and comfortable operation can be performed. Further, in this example, the film member 30 is partially removed to form the opening 30a. Therefore, the region where the film member 30 and the touch panel 4 pass through the adhesive 41 is the peripheral region of the touch panel 4 (front side substrate 8a). The width of the edge region differs depending on the size of the touch panel 4, but the thickness can be ensured to a few mm, so that the bonding strength of the film member 30 control panel 4 can be ensured. However, when compared with the input 4 0 A, 4 0 B shown in Fig. 1, the bonding area is narrow, the bonding strength is low, and 40B is formed, that is, the weight is omitted. 4 6a is inserted into the front row to the side base through the device. The mouth portion is bonded to the touch device in the past. Therefore, the input device 40C' in this example is the same as the input device 40B. The adhesive 4 4 is disposed in the gap between the touch panel 4 and the cover member 45. The adhesive cover member 45 and the touch panel 4 are preferred. Further, in the case of the present example, the light-shielding film 46 formed on the side of the covering member 45 of the film member 30 is preferably formed on the outer side of the opening portion 30a of the film member 30 by bonding the film member. The adhesive 4 of the touch panel 4 and the touch panel 4 covers the configuration of the light shielding film 46. With such a configuration, the light shielding film 46 is not exposed in the opening portion 30a, so that peeling of the interface between the light shielding film 46 and the film member 30 can be prevented, and the light shielding film 46 can be effectively protected. Further, in the case of the present example, the structure of the front side substrate 8a of the front surface of the touch panel 4 is such that the substrate body 11a of the front side substrate 8a is a glass substrate. When the glass substrate is damaged, the fragments will scatter everywhere. That is, in the case of the configuration shown in this example, it is preferable to use a high-strength glass substrate or a plastic substrate as the substrate main body 1 1 a of the front side substrate 8 a . Alternatively, it is preferable to form a protective layer by coating a transparent resin or the like on the surface of the substrate main body 1 1 a. [Fourth configuration example] Fig. 5 is a schematic cross-sectional view of the input device 40D of the fourth configuration example of the input device of the first embodiment, which corresponds to Fig. 1 (a) and Fig. 1 (b) . As shown in Fig. 5, the input device 4A of the present configuration example has a basic configuration of the input device 40B according to the second configuration example, and is further disposed on the cover member 45 side of the film structure-24-200903074 Polarizing plate 6a. The polarizing plate 6a can be an optical element which is a display means such as a liquid crystal panel disposed on the back side of the touch panel 4 (the side opposite to the film member 30). According to the input device 40D having the above-described configuration, since the polarizing plate 6a and the film member 30 are disposed on the front surface side of the touch panel 4, the operating pressure of the touch panel 4 is increased as compared with the case where only the film member 30 is provided. The protection of the touch panel 4 is more certain. Further, when the touch panel 4 having the glass substrate is broken, the scattering of the glass can be effectively prevented. Further, in this embodiment, the polarizing plate 6a is disposed between the film member 30 and the light shielding film 46, but the polarizing plate 6a may be disposed between the light shielding film 46 and the covering member 45. Alternatively, the polarizing plate 6a and the touch panel 4 are disposed in the accommodating portion 45a at the same time. Further, when the polarizing plate 6a has sufficient durability, the polarizing plate 6a may be used as a flexible member that is bonded to the touch panel 4 and the covering member 45 without providing the film member 30. Further, between the film member 30 and the covering member 45, it is not limited to the polarizing plate, and other optical elements may be disposed. For example, a laminated polarizing plate 6a and a λ/4 phase difference plate, or an optical element (circular polarizing plate) in which the polarizing plate 6a and the λ/4 phase difference plate and the λ/2 phase difference plate are laminated may be disposed. Further, an antireflection film or a light diffusion film may be disposed. [Fifth Configuration Example] Fig. 6 (a) is a schematic cross-sectional view showing an input device 40E of a fifth configuration example of the input device of the first embodiment. Fig. 6 (a) corresponds to the figures of Fig. 1 (a) and Fig. 1 (b). -25-200903074, as shown in Fig. 6 (a), the input device 40E of the present configuration example has a basic configuration of the input device 40B according to the second configuration example, and further, from the back side of the touch panel 4 (and The film member 30 (the opposite side) covers the touch panel 4 and the cover member 45 so as to be bonded to the film member 3 1 (second flexible member). Further, the flexible printed circuit board 16a pulled out of the terminal by the touch panel 4 is pulled out to the outside through the slit-like opening provided in the film member 31. As the film member 31, similarly to the film member 30, a film material made of a transparent resin such as polyethylene, polyester or polypropylene such as PET (polyethylene terephthalate) can be used. . The thickness of the entire input device 40E can be prevented from increasing by adhering the film member. Preferably, the film member 31 is bonded to both the back side substrate 3b of the touch panel 4 and the cover member 45, and the film member 31 and the touch panel 4 are preferably optically bonded. However, if at least the film member 31 and the cover member 45 are bonded, the movement of the touch panel 4 in the thickness direction of the touch panel 4 is restricted by the film member 31 and the film member 30, so that the film member 31 and the touch panel 4 are not It is bonded, and even a gap is formed between the film member 31 and the touch panel 4. According to the input device 40E having the above-described configuration, the thin film member 31 is disposed on the back side of the touch panel 4, and the touch panel 4 is sandwiched by the film members 30 and 31. When the input operation is performed, it is possible to prevent the touch surface -26-200903074 board 4 from being pressed down by the pressing force of the input device 3 or the finger or the like. Further, the film member 31 may be a polarizing plate or a phase difference plate in addition to the transparent film described above. Further, 'not limited to a single optical element, a laminated polarizing plate and a λ/4 phase difference plate' or a laminated polarizing plate and an optical element of a λ/4 phase difference plate and a λ/2 phase difference plate (circularly polarized light) board). Further, a light diffusion film may be disposed. [Sixth Configuration Example] Fig. 6 (b) is a schematic cross-sectional view showing an input device 40F of a sixth configuration example of the input device of the first embodiment. Figure 6 (b) corresponds to Figure 1 (a) and Figure 1 (b). As shown in FIG. 6(b), the input device 40F of the present configuration example has the basic configuration of the input device 40E according to the fifth configuration example, and is further bonded to the back side of the touch panel 4 (and the film). The film member 31 (second flexible member) on the opposite side of the member 30 is formed into the opening portion 3 1 a. The opening portion 31a is formed to have a planar region that substantially coincides with the plan view of the opening portion 46a of the light shielding film 46. According to the input device 40F having the above-described configuration, the thin film member 31 is disposed on the back side of the touch panel 4, and the touch panel 4 is sandwiched by the film members 30 and 31. When the input operation is performed, the touch panel 4 can be prevented from being pressed by the pressing force of the input device 3 or the finger or the like. In addition, when a display means such as a liquid crystal panel is disposed on the back side of the touch panel 4, for example, when the opening portion 31a is formed, a film is not disposed in a region displayed on the board 4 through the touch surface -27-200903074. Since the constitution of the member 31 is such that light loss or refraction due to the film member 31 is not caused, and the reflection at the interface 'can be seen, the quality of the cylinder can be clearly seen. In the present embodiment, since the opening portion 31a is formed in the film member 31, the film member 31 is configured to support the peripheral edge portion of the touch panel 4. That is, it is preferable to adhere the film member 31 to the back side substrate 8b of the touch panel 4 in such a manner that the touch panel 4 is stably supported by the film member 31, and the above embodiment is shown as an example. In the configuration of the input device of the present invention, the configuration of each component can be variously changed. For example, the touch panel 4 may have a buffer structure in which a liquid material for adjusting the refractive index is sealed in a space surrounded by the front side substrate 8 a, the back side substrate 8 b, and the sealing member 9 . As the liquid material sealed between the front side substrate 8a and the back side substrate 8b, it is preferable to use eucalyptus oil or the like having a refractive index difference smaller than that of air. When a liquid material such as a liquid crystal panel is disposed on the back side of the touch panel, the light emitted from the display means can be prevented from being reflected on the back side substrate 8b and the space or the space rain front side substrate 8 The interface of a is reflected, so that a bright display through the touch panel 4 can be realized. Further, by enclosing the liquid material between the substrates, this can function as a buffer, and when the front side substrate 8a is impacted, it can be relaxed. In short, in the present embodiment, since the coordinate input faces of the front side substrates 8a-28-200903074 are made thinner than the plate thicknesses of other portions, although the resistance is weaker than the usual mechanical shock, the buffer is provided. The structure can compensate for the impact resistance by reinforcing the part. In consideration of the aforementioned buffering function, the viscosity of the liquid material is, for example, in the range of 2 mm 2 /s to 5000 mm 2 /s. Further, if it is considered separately, the touch panel 4 of the resistive film type can be replaced, and the touch panel of the electrostatic capacitance type can be used. In the case of a capacitive touch panel, the thickness of the touch panel is substantially sufficient, and the accommodating portion 45 a of the covering member 45 or the covering member 45 itself can be thinned, so that an input device can be obtained. The 40A and 40B are all thinned. Further, in the present embodiment, the configuration in which the touch panel 4 is housed in the accommodating portion 45a formed to penetrate the cover member 45 is described. However, the structure of the accommodating portion 45a can be variously formed by the shape or thickness of the touch panel 4. change. For example, a locking member such as a protrusion that protrudes into the accommodating portion 45a may be provided in the covering member 45, and the movement of the touch panel 4 in the thickness direction of the touch panel 4 may be restricted by the associated locking member. Further, when it is used for the purpose of not providing the display means on the back side of the touch panel 4, the accommodating portion 45a may be a concave portion formed on one surface side of the covering member 45. When the touch panel 4 is disposed in the accommodating portion 45a formed of such a concave portion, the positional restriction of the touch panel 4 becomes extremely easy. Further, the film member 30 that is bonded across the touch panel 4 and the covering member 45 is provided. The flatness of the surface also becomes easy to ensure. [Second Embodiment] -29-200903074 Next, a photovoltaic device according to a second embodiment of the present invention will be described with reference to Figs. 7 to 9 . Fig. 7 (a) is a schematic cross-sectional view showing a first configuration example of a liquid crystal device of a touch panel integrated type according to the photoelectric device of the second embodiment. Fig. 8 is a schematic cross-sectional view showing a liquid crystal device of a second configuration example. Fig. 9 is also a schematic cross-sectional view showing a liquid crystal device of a third configuration example. In the present embodiment, the input device provided in the liquid crystal device is described as an input device 40B according to the second configuration example of the first embodiment or an input device 40D according to the fourth configuration example, but instead of the input. The devices 40B and 40D may be used as the input devices 40A, 40C, 40E, and 40F of other configuration examples. [First configuration example] The liquid crystal device 100A according to the first configuration example shown in Fig. 7 (a) is configured to include a liquid crystal panel (photoelectric panel) 2 of a display portion, and is disposed on the front side thereof ( The input device 40B of the first embodiment of the upper side and the observation side is shown. As described above, the input device 40B includes an analog type resistive film type touch panel (input panel) 4, and a cover member 45 for accommodating the accommodating portion 45a of the touch panel 4, covering the touch panel 4 and the cover member 45. The film member 30 is bonded to the main surface 45s of the cover member 45 and the main surface 4s of the touch panel 4. The liquid crystal panel 2 is composed of a translucent elastomer (for example, a gel having a refractive index difference smaller than that of air, an acrylic gel, an amino-30-200903074 ethyl formate gel, an amino group) The adhesive 50 of a translucent elastomer such as ethyl formate rubber is optically bonded to the back side substrate 8b of the touch panel 4. By forming the adhesive 50 by the elastic body, the elastic body absorbs the pressing force when the input operation of the touch panel 4 is performed, and it is possible to suppress the display failure of the substrate of the liquid crystal panel 2 due to the input operation due to the strain. . Since the elastomer absorbs the pressing force, it is preferably 50 to 50,000 μm. Further, since it is optically connected to the back side substrate 8b of the touch panel 4, a gap (air layer) between the substrate 8b and the back side of the touch panel 4 is no longer formed. The adhesive agent 50 has a smaller refractive index difference from the glass than air, and can be suppressed on the back surface of the touch panel 4, for example, by ambient light incident on the front substrate (first substrate) side of the touch panel 4. The light reflected from the interface between the surface of the side substrate (second substrate) lib and the air layer is reflected by the light reflected from the interface between the air layer and the surface of the front substrate (third substrate) 22a of the liquid crystal panel 2, and is reflected. Very few vivid displays. In order to obtain such an effect, it is necessary to make the refractive index of the elastomer included in the adhesive 50 close to the refractive index of the glass substrate or the plastic substrate constituting the touch panel 4 and the liquid crystal panel 2, and the refractive index is preferably 1. 4~1. 9. In the liquid crystal panel 2, the front side substrate (the third substrate) 22a and the back side substrate which are opposed to each other by the liquid crystal (photoelectric substance) 32 are formed by the annular sealing material 2 in the peripheral portion of the two substrates. (4th substrate) 22b is bonded to the body. The front side substrate 22a disposed on the observation side has a front side electrode 26a or an alignment film (not shown) formed of a transparent conductive material on the liquid crystal layer side surface of the substrate main body 24a of the transparent substrate. -31 - 200903074 The composition of the LCD control layer. The back side substrate 22b disposed on the opposite side of the observation side (the side opposite to the rain front side substrate 22a of the layer 32), and the back surface of the substrate body Mb of the transparent substrate having the shape of a transparent conductive material The configuration of the liquid crystal control layer such as the side electrode 26b or the alignment film (denoted). The granular spaces 29 for maintaining a constant distance (cell gap) between 22a and 22b between the front side substrate 22a and the back side substrate 22b are dispersed. The liquid crystal panel 2 can be either a passive matrix type or a main array type, and the alignment type of the liquid crystal can also be of various conventional types such as TN type, type, S TN type, ferroelectric type, and anti-strong dielectric type. Further, a color filter may be disposed on any of the substrates to perform display. Further, a liquid crystal display device may be formed by forming a reflective film on the back side substrate 22b, and the reflective film may have an opening portion or a slit light portion to constitute a transflective liquid crystal display device. The front side substrate 22a is provided with a projecting portion 24c that protrudes toward the side of the back side substrate 22b. This projecting portion 24c is used as a mounting terminal region. The projecting portion (not shown) is formed in the projecting portion 24c, and the front side electrode 2 6 a of the front side substrate 2 2 a and the back side electrode 26 b of the back side 22 b are electrically connected through a wiring pattern or a material (not shown). The wiring pattern of the extension portion 24c. Next, for the wiring pattern of the extension 24c, the drive 1C (electronic component) 36 of the liquid crystal panel 2 is electrically driven by the COG. As the type of 1C 36 for liquid crystal driving, in addition to COG mounting, FPC mounting or the like can be used. The liquid crystal is formed in the substrate by the spacer spacer VAN bear. In the present embodiment, the projection portion 24c' of the liquid crystal panel 2 is superposed on the terminal portion 16 of the touch panel 4 by the color projection type and the like. The touch panel 4 and the liquid crystal panel 2 are disposed in a manner of forming a region (a region in which the back surface 俚J substrate 8 b protrudes more than the front substrate 8 a ). The frame edge region of the liquid crystal panel 2 is also covered by the light shielding film 46. Further, the area where the back side substrate 8b of the touch panel 4 and the front surface side substrate 2 2 a of the liquid crystal panel 2 overlap can be maximized, so that the adhesion reliability of the touch panel 4 and the liquid crystal panel 2 can be improved. Further, the area where the connection terminal of the external circuit is formed is such that the touch panel 4 is disposed close to the liquid crystal panel 2, so that the connection to the external circuit can be easily performed. Further, although not shown in the drawings, a polarizing plate is provided on the outer surface side of the front substrate 22a of the liquid crystal panel 2 and the outer surface side of the back substrate 22b. Either of the pair of polarizing plates may be provided on the liquid crystal layer 32 side of the substrate body 24a or the substrate body 24b. Further, an illumination device (backlight) is disposed on the outer side of the back side substrate 22b. According to the liquid crystal device 1A of the present embodiment having the above configuration, since the input device 40B of the first embodiment and the liquid crystal panel 2 that is bonded to the touch panel 4 of the input device 40B are provided, the liquid crystal device 1A can be performed. Through the display of the touch panel 4. Further, by arranging the liquid crystal panel 2 on the back side of the touch panel 4, the movement of the touch panel 4 in the thickness direction of the substrate is restricted by the liquid crystal panel 2 or the housing supporting the liquid crystal panel 2, and the like. The touch panel 4 is pressed down by the pressing force during the operation. Next, in the liquid crystal device of the present embodiment, the display surface side is flattened by the film-33-200903074 member 30, and the film member 30 can be subjected to any printing, so the degree of freedom in design is high. 'Become a liquid crystal device that can obtain excellent patterns. Further, in the liquid crystal device of the present embodiment, the film member 30 is disposed on the front side of the touch panel 4, so that the touch panel 4 using the glass substrate on the front side substrate 8a can be used safely. The touch panel of the glass substrate is used for both of the two substrate bodies 11a and 1 , and the substrate body 11a is a plastic substrate, or both of the substrate bodies 11a and 11b have a high transmittance, so that the transmittance is high. A brighter and taller display is available. Further, in the present embodiment, the liquid crystal panel 2 is configured to protrude from the covering member. However, if the covering member 45 has a sufficient thickness, the crystal panel 2 and the touch panel 4 may be housed in the housing 45a of the covering member 45. . With such a configuration, the adhesive member can be disposed between the liquid crystal panel 2 of the cover member 45 to bond the both. Therefore, both the touch panel 4 and the liquid crystal panel 2 can be stably supported by the member 45. On the other hand, when the back side of the liquid crystal panel 2 (the side opposite to the touch panel 4) is provided with a backlight, it may be configured to accommodate the backlight in the housing portion 45a. However, in the configuration of the touch panel 4 on the front side of the liquid crystal panel 2 as in the present embodiment, when the input operation is performed by pressing the surface of the touch surface 4 with the finger or the input device 3, the display of the liquid crystal panel 2 is caused. Distortion. This is because the local deformation of the touch panel 4 is caused by the pressing force at the time of input, thereby deforming the new panel lb and the cover member provided on the back side of the touch panel 4. The setting of the board -34- 200903074 A very small amount of deflection occurs on the front side of the liquid crystal panel 2. The gap of the total crystal panel 2 is about 1 μm to 10 μm, so even if the deflection of the front plate 2 2a is only slightly, the deflection causes the liquid crystal panel gap to locally vary at a large ratio, and as a result, an image is produced on the display. It is dry twisted. Such a problem can be solved by making the thickness of the back surface 22b of the liquid crystal panel 2 sufficiently thin. For example, the thickness of the back side substrate is thinned to 0. 1mm~0. The substrate is easily spliced to the extent of 4 mm, and as described above, even if the front side substrate 22a of the liquid crystal panel 2 is curved, the flexing back side substrate 22b follows the deflection ‘with little change. However, when the substrate is thinned as described above, the substrate becomes difficult, and the resistance to mechanical shock may be deteriorated in the manufacturing step, and the mechanical shock resistance may be deteriorated. Therefore, in the case of carrying, the drop may occur. And the problem that caused the damage. In the case of the operability or impact resistance of the substrate, the thicker the substrate is, the thinner the substrate is, the better the surface quality is. Here, in order to satisfy the requirements of both parties, the liquid crystal panel 2A having the configuration of FIG. 7(b) can be used. The glass substrate of the thick liquid crystal is used for the substrate 22a in the related liquid crystal panel 2A' to improve the operability, and the other corresponds to the back side. The portion of the display region of the substrate 22b is formed (thin-plate region) and is thinned to be configured to follow the deformation of the substrate 22a at the time of input. Specifically, for example, the front surface 22a and the back side substrate 22b (portions where the concave portion is not formed) The thickness is 〇. At about 5 mm, the concave portion of the back side substrate 22b is formed, and the field of the curved side substrate 22b between the liquid surface side bases 2 is subjected to the operation of the deflection. The use of this is better, as shown in the front side, the recess Η front side of the side substrate substrate area -35- 200903074 substrate thickness is 〇. Lmm~0. 4mm level. Further, as described above, when the concave portion 形成 is formed on the back side substrate 2 2 b of the liquid crystal panel 2, as shown in the figure, it is preferable to accommodate the polarizing plate 6b in the concave portion. In addition, when an optical film used together with a polarizing plate such as a phase difference plate is used, it may be accommodated in a concave portion together with the polarizing plate. When the configuration is such a configuration, the liquid crystal device can be made thinner in terms of the thickness of the optical film such as a polarizing plate. [Second Configuration Example] Next, a second configuration example of the present embodiment will be described with reference to Fig. 8 . As shown in FIG. 8, the liquid crystal device 100 Β of the second configuration example includes the input device 40A of the first embodiment and the liquid crystal panel 2A. The liquid crystal panel 2 is basically the same as the liquid crystal panel 2 according to the first configuration example, and only the panel size is different. Specifically, the liquid crystal panel 2 is a substrate having a front surface area larger than the accommodating portion 45a of the covering member 45. Then, the liquid crystal panel 2B is adhered to the back side substrate 8b of the touch panel 4 via the adhesive 50, and is also bonded to the inner surface 45b of the cover member 45. In the method of bonding the covering member 45 and the liquid crystal panel 2, in addition to the method of separately applying an adhesive between the covering member 45 and the liquid crystal panel 2, the adhesive 50 may be extended to the covering member 45. The method of bonding the cover member 45 to the liquid crystal panel 2 by the adhesive 50 or the adhesive 4 2 of the adhesive contact panel 4 and the cover member 45 is extended to the back surface 45b of the cover member 45. The method of bonding. -36-200903074 The liquid crystal device 100B' of the present embodiment having the above-described configuration is disposed on the front side substrate 2 2 a of the liquid crystal panel 2 on the back side of the touch panel 4, and is bonded to the back surface 45b of the cover member 45, Therefore, the touch panel 4 is fixed to a space surrounded by the film member 30 and the liquid crystal panel 2 and the cover member 45, and is kept stable. Further, in the second configuration example shown in Fig. 8, the adhesive 50 for bonding the liquid crystal panel 2 to the touch panel 4 may be omitted. In the second configuration example shown in FIG. 8, the liquid crystal panel 2, the touch panel 4, and the cover member 45 are bonded to each other via the adhesive 50, the adhesive 42, and the like, so that the liquid crystal panel 2 is supported most stably. And the configuration of the touch panel 4. On the other hand, the composition of the parts adhered by the adhesive is so much because of the large number of work, and the raw materials are also required. For this reason, in the present configuration, by omitting the adhesive 50 of the adhesive contact panel 4 and the liquid crystal panel 2, the liquid crystal device can be manufactured at a low cost while reducing the number of operations. Further, in the case of such a configuration, a gap (air layer) is formed between the touch panel 4 and the liquid crystal panel 2, so that the pressing force at the time of the input operation of the touch panel 4 becomes difficult to be applied to the liquid crystal panel 2. Thereby, occurrence of display failure due to distortion of the liquid crystal panel 2 can be prevented. [Third configuration example] Next, a third configuration example of the present embodiment will be described with reference to Fig. 9 . The liquid crystal device i〇〇c according to the third configuration example shown in Fig. 9 is a configuration in which the polarizing plate is changed in relation to the liquid crystal device 100A in the first configuration example. -37-200903074 As shown in Fig. 9, the liquid crystal device 1 〇 0 C of the present configuration includes an inverter 40D and a liquid crystal panel 2. The input device 40D has a basic configuration of the input device 4A of the second configuration example of the first embodiment, and further includes a front side polarizing plate (the first polarizing plate) on the side of the film member 30 covering member 45. 6 a ° In addition, on the side opposite to the liquid crystal layer of the back side substrate 22b of the liquid crystal panel 2, a back side polarizing plate (second polarizing plate) 6b which is paired with the front side polarizing plate 6a is disposed. In the liquid crystal device 100C of the present configuration, one of the front surface and the back surface of the liquid crystal panel is disposed on the polarizing plate, and the light panel disposed on the front side is disposed outside the touch panel 4. The liquid crystal device having the above configuration is provided. 100 C, since the front side light plate 6a and the film member 30 are disposed on the front side of the touch panel 4 (the side opposite to the liquid crystal panel 2), the case of the touch panel 4 is the case only with the film member 30. The operating pressure is increased, and the protection of the touch panel 4 is more reliable. Further, when the touch panel 4 having the glass substrate is broken, the scattering of the glass is more effectively prevented. Further, since the front side polarizing plate 6a is disposed on the touch panel 4 Side, so the cover can be The total thickness of the touch panel 4 and the liquid crystal panel 2 which are disposed on the back side (the side opposite to the film member 30) is thinned, and the liquid crystal package 100C can be saved. The space inside the housing of the electronic device can be reduced in size. 3 2 The surface of the optical surface is out of phase with the outer surface type -38- 200903074 Also, in this example, the front side polarizing plate 6a is disposed. Between the film member 30 and the light shielding film 46, the front side polarizing plate 6a may be disposed between the light shielding film 46 and the covering member 45. Alternatively, the front side polarizing plate 6a and the touch panel 4 may be disposed in the accommodating portion 45a at the same time. Further, when the front side polarizing plate 6a has sufficient durability, the front side polarizing plate 6a may be used as a flexible member to be bonded to the touch panel 4 and the covering member 45 without providing the film member 30. [Third Embodiment] Fig. 10 (a) is a schematic cross-sectional view of an input device 40A according to a first configuration example of a third embodiment of the present invention. Fig. 1 b (b) The same phase is a schematic cross-sectional view of the input device 40B of the second configuration example. Figure 11 is a schematic plan view of the input device 40A shown in Figure 10. Fig. 12 is an exploded perspective view showing the configuration of the touch panel 4. [First configuration example] As shown in Figs. 10 and 11, the input device 40A of the present embodiment includes a cover member 45 having a substantially planar shape in plan view, and is disposed on a rectangular shape formed by the cover member 45. A touch panel (input panel) 4 of an analog type resistive film type in the accommodating portion 45a formed by the opening portion, and a main surface 45s (front side of FIG. 11) of the straddle cover member 45 and the touch panel 4 The film member 30 whose main surface is bonded for 4 s. The end portion on the main surface 45s side of the accommodating portion 45a of the covering member 45 is formed to be the inner wall of the accommodating portion 45a in a plane-like frame-like panel supporting portion 45A (shown by the oblique line pattern -39-200903074). Extend out. The panel supporting portion 45A has supported the touch panel 4 in such a manner that the peripheral portion of the touch panel 4 is pressed by the film member 30 side. The panel supporting portion 45A has a rectangular opening portion 45b on the touch panel 4. On the side of the covering member 45 of the film member 30, a light-shielding film 4 ό formed by printing, for example, a light-shielding film 46 having a rectangular opening in a plane region corresponding to the input portion 40a of the touch panel 4 is formed. 46a. The light shielding film 46 is formed so as to cover the cover member 45 in a plan view, and the opening 46a of the light shielding film 46 is disposed on the inner periphery of the opening portion 45b of the panel support portion 45A so as to be larger than the opening portion 4. 5 b is more inside. The thickness of the touch panel 4 is almost the same as the depth of the accommodating portion 45a of the cover member 45, and the touch panel 4 is housed in the accommodating portion 45a of the cover member 45, so that the main surface of the touch panel 4 is 4 s. The inner surface of the panel supporting portion 45 A (the surface on the side of the touch panel 4) is in contact with each other. Next, on the back side of the touch panel 4 (the side opposite to the film member 30), a back surface (a surface opposite to the film member 30) and a back surface of the cover member 45 are disposed. The back side film member 31 is bonded to (the surface opposite to the film member 30). In the input device 40A, the touch panel 4 is supported by the cover member 4 in a state in which the frame-shaped panel support portion 45A and the back-side film member 31 are held by the panel in the thickness direction of the panel. 5. Further, the flexible printed circuit board 16a pulled out of the terminal by the touch panel 4 is pulled out to the outside through a slit-like opening portion (not shown) provided on the back side film member 31. Further, as the back side film member 31, a transparent tree such as polyethylene (polyethylene terephthalate) such as PET, polyethylene terephthalate or the like can be used as the film member 30 of the thin-40-200903074 film. A film material composed of an ester material. Next, the film member 30 disposed to cover the cover member 45 and the touch panel 4 in plan view is arranged to follow the main surface 45s formed on the cover member 45 and the opening 45b exposed to the panel support portion 45A. The shape of the step of the boundary portion of the main surface 4s of the touch panel 4 is adhered to the cover member 45 and the touch panel 4. In short, on the flat cover member 45 and the panel supporting portion 45 A, and also on the touch panel 4, the surface of the film member 30 is a flat surface. On the other hand, the film member 30 is deformed and closely adhered to the step portion between the main surface 4s of the touch panel 4 formed by the opening 45b of the panel supporting portion 45A and the main surface 45s of the covering member 45. The surface of the stepped member, as a result, also forms a step portion 43 on the surface of the film member 30. Further, as will be described later in detail, the film member 30 is brought into close contact with the touch panel 4 and the covering member 45 in such a manner that the film member 30 can be temporarily softened by a thermal fusion method or a vacuum thermal fusion method. It can be carried out extremely easily. In the touch panel 4, the front side substrate (first substrate) 8a and the back side substrate (the first substrate) having a predetermined gap are formed by the annular sealing material 9 in the peripheral portion of the two substrates 8a and 8b. 2 substrate) 8b bonding integration. As shown in FIG. 12, the front side substrate 8a of the touch panel 4 is attached to the inner surface (surface on the back side substrate side) of the substrate body 11a of the transparent substrate, and -41 - 200903074 is formed by transparent conductive The same planar shape pole (high-resistance film; first electrode) 12a made of a material is formed at both end portions of the planar electrode 12a in the Y direction (portion of the rectangular planar electrode 1 2 a) The composition of the low-resistance film 13 is obtained. The low-resistance film 13 formed on the front plate 8a is transmitted through the conductive material 17, and is electrically connected to the auxiliary electrode 18 on the back side substrate 8b, and is further pulled out to the terminal portion 16 through the auxiliary 18. The low-resistance films 13 and 14 and the wiring portion constituting the touch panel 4 are formed along the substrate 8a or the edge portion of the substrate. On the other hand, the back side substrate 8 b of the touch panel 4 is formed on the inner surface (the surface on the front substrate side) of the substrate body 1 1 b of the material to have the same planar shape surface made of a transparent conductive material. (high-resistance film; second electrode) 12b is formed at both ends in the direction of the planar electrode 12b (the pair of low-resistance films 14 are formed on opposite sides of the rectangular planar electrode 12b. The substrate 8b is formed with a terminal portion 16 that is connected to the low-resistance film 13 and the low-resistance film 14 from the terminal portion 16. The terminal portion 16 is shown in Fig. 10, and the flexible printed circuit ACP (Anisotropic Conductive) Paste, anisotropic conductive ACF (Anisotropic Conductive Film), the terminal portion 16 is electrically connected to an external control circuit. In this embodiment, the outer side surface of the front side substrate 8 a and the electrode 12a The planar area of the formation area is a coordinate input surface (the positional surface of the touch panel is directly indicated by the input device 3 or a finger or the like. The both end faces are based on the peripheral transparent base forming the auxiliary electrode 1 8 8b, and are shaped electrodes Figure X end) Side end plate via wiring phase slurry) or a) is coupled becomes the operation surface corresponding to the surface 200 903 074 performed by the operation input -42-). A hard glass substrate is used for each of the substrate bodies 1 1 a and 1 1 b constituting the front side substrate 8a and the back side substrate 8b. Since the front side substrate 8a is a glass substrate, there is no problem that the substrate or the electrode is deteriorated as in the case where the plastic substrate is used for the front substrate. On the other hand, a rigid glass substrate lacks flexibility as compared with a plastic film substrate. Therefore, if the pressing load at the time of input is too small, the input may not be sufficiently performed. Therefore, in the present embodiment, the thickness of the glass substrate is made thinner to 0. 1 mm~ 0. 2mm degree to solve the problem of operability. On the other hand, as the substrate main body 1 1 b constituting the back side substrate 8 b, the same thickness as that of the liquid crystal panel or the like is used. For example, in this example, the thickness of the back side substrate 8b of the touch panel 4 is made 0. 5mm level. The planar electrodes 12a and 12b are made of a transparent conductive film such as ITO (Indium Tin Oxide), and have almost uniform surface resistance over the entire area in the plane. On the other hand, the 'low-resistance films 13 and 14 and the auxiliary electrode 18 and the terminal portion 16 are made of a conductive metal thin film such as Au, Ag, Cu, Al, Cr, or any one of these metals. The alloy is formed. In the present embodiment, since the glass substrate is used as the substrate body of the front side substrate 8 a and the back side substrate 8 b , unlike the prior touch panel using the plastic film substrate, high temperature heat treatment or etching using a strong acid etching solution can be performed. deal with. Therefore, in the present embodiment, the conductive films (the planar electrodes 12a and 12b, the auxiliary electrode 18, the terminal portion 16, and the like) for detecting the coordinate information are all subjected to a vacuum process such as sputtering or vapor deposition. In the case of 200903074, the low-resistance films 13 and 14 and the auxiliary electrode 18 are thinned by an etching process to form a wiring portion having a narrow frame edge. For example, when APC (AgPdCu alloy, specific resistance is about 4x10_6Qcm) is used in the wiring portion, the pull-back wiring made of silver paste and having a thickness of 20 μm and a line width of 1 mm can be made to have a thickness of 0 at A P C. 2 μ m, line width 0. 1 m m. In addition, the specific resistance (Qcm) of copper, aluminum, and chromium is 6χ10_6, 6χ1 (Γ6, 5 X 1 〇_5, respectively, so even if these metals are used, the line width can be narrower than before. 1 to 2 orders of magnitude. The buffer member 15 made of a resin material or the like is arranged on the planar electrode 1 2 b of the back side substrate 8 b. The buffer member is preferably made of an elastic material such as enamel resin or urethane. (for example, the elastic modulus is in the range of 1 X 1 04 N/m 2 to 1 X 1 08 N/m 2 ), formed on the planar electrode 1 2 b by photolithography or printing. This buffer structure also serves as the control substrate 8 a A spacer for the gap of 8 b functions. As the film member 30 bonded to the touch panel 4, polyethylene (polyethylene terephthalate) or the like can be used. a film material made of a transparent tree vinegar material such as a storage, a polyester, or a polypropylene storage. When the input device 40A performs a coordinate input operation on the touch panel 4, the input device 3 or a finger or the like slides on the surface of the film member 30, or On the back side of the touch panel 4 (film member 3) The display device is used as a display device by providing a display means such as a liquid crystal panel. Therefore, as the film member 30', it is preferable to prevent wear due to the operation, or to cover the surface of the member 45 or the touch panel 4. Further, it is preferable that a PET film having a good transmittance can be obtained. -44- 200903074 is formed on the cover member 45 side 46 of the film member 30, for example, by coloring a black material or a white material by printing. In the case of the present embodiment, the region where the touch panel 9 is formed or the portion where the terminal portion 16 is formed functions, and is disposed on the back side of the touch panel 4 (the opposite side of the film structure). In the case of a display means such as a liquid crystal panel, it functions as a side shield. The light-shielding film 46 has a color which can be used as a mask, and a pattern is attached to the film member 30 on the film member 30 side, and not only the light-shielding film 46 but also a color A design formed by a pattern. The related design may be formed on either side of the member 30, but formed on the side of the covering member 45 from the viewpoint of protecting the printed matter. The covering member 45 is made of plastic. The rubber sheet or the metal sheet may be formed of a substrate having a specific strength, and is not particularly required. 4 5, not only as a support for the touch panel 4, but also for use as a member of an operation panel of a sub-machine, in this case The operation unit built in the control panel is used. When the input device 40 is used as the electronic device, the cover member can be used as a through hole for a button or a switch, and such processing can be easily realized by lending. Character information such as a description of a printable button or a switch is applied to the film member 30. The input device of the present embodiment having the above-described configuration is formed in the accommodating portion 45a of the cover member 45, and the main surface 4s of the touch panel 4 is disposed. The light-shielding film of the surface of the main surface 45s of the cover member 45 may be formed to have a light-tightness of the panel 4 as a relative display of the shield member 30. It is preferable to use it as a film, and it is preferable that the cover member is provided as an operation portion 45 which is electrically configurable as a contactor, and is punched or cut to be printed, 40A, in the plate 4, across the touch panel Bonding film-45-200903074 Member 30, and further, the film is bonded in accordance with the step shape between the main faces 4 5 s of the touch panel 4 and the main faces 4 5 s of the 4 5 s. Therefore, the cover frame having the different materials and the touch panel have a clear boundary and step difference, and the surface of the film member 30 has a smooth continuous step shape and is comparable to the previous one. The surface is excellent in appearance, and the degree of freedom can be increased, making it an excellent input device for new styles. Further, if there is a combination between the touch panel and the casing as before, there is a problem that dust is accumulated in the step difference, or a gap in which the water droplets adhere to the gap portion is immersed in the casing, but the covering member 45 is actually included. The film member 30 is entirely covered, and the accumulated dust is damaged and beautiful, or the water droplets are immersed in the trouble, and the input device is excellent in reliability. In the present embodiment, the film member 30 of the step of the main surface 4 s of the main face control panel 4 of the covering member 45 is closely connected, and it is preferable to form the panel supporting portion 45A 4 which constitutes the aforementioned step. 5b is formed in a shape that widens the side of the film member 30, that is, it is preferable that the cross-sectional end faces are formed in a bevel shape (push-out shape). In addition, in thickness 〇 · 1 ~ 〇. The front side substrate 8a of the touch panel 4 made of a thin glass of about 2 mm is adhered to the film structure. Even if the front side substrate 8a is joined by the impact of falling or foreign matter, the glass member can be prevented from flying by the film member 30. An input device with excellent safety. In particular, the present embodiment 30 covers a cover member 30 that contains the touch panel 4 and the cover member 45 (or an implementation type. Therefore, the high-designed step of the field water droplets from the step mode, Therefore, it is not allowed to be bonded by the upper substrate of the upper side of the opening pattern of the 45s and the more favorable one, and the rupture of the field is sturdy, and the film facet is bonded -46 - 200903074, so the film member 3 In addition, in the input device 40A of the present embodiment, the state in which the movement of the member 30 side is restricted by the panel supporting portion 45 of the covering member 45 is touched. That is, even if the touch panel produces a manufacturing error, the height of the step between the main faces 4 s of the main control panel 4 of the covering member 45 is not so bad that the film member 30 is stably adhered to the step. In the present embodiment, the touch panel 4 is placed in the accommodating portion 45a by abutting against the 45A, and the touch panel is fixed by the back side film member 31 attached to the cover f side. 4. By a fixed method, a simple step Further, the touch panel 4 is mounted, and the adhesive may be adhered between the main surface 45s of the covering member 45 and the film structure 46). Further, the main surface 4s and the surface of the touch panel 4 of the film member 30 are optically bonded to each other to optically bond the film member: the plate 4 is also possible. As the adhesive (adhesive) provided between the film member 30 and the covering member 45 (4), various kinds of adhesives such as a acryl resin and a enamel resin can be used. In the case of the optical adhesive film structure control panel 4, an eucalyptus-based adhesive is preferably used. The input operation and manufacturing steps of the touch panel 4 are as described. It also has the control panel 4 which has a thickness of 45 s to the film structure 4 and is different from the touch, so it is possible to enter the back of the panel support portion of the cow 45. Pieces 3 0 (between the light-shielding touch panel 4, with 〇 and touch surface and touch panel force system, rubber parts 30 and touch 1st implementation type -47- 200903074 <Manufacturing Method of Input Device According to First Configuration Example> Next, a method of manufacturing the input device 40A according to the first configuration example will be described with reference to Figs. 13 and 14 . 13 and 14 are schematic cross-sectional views showing the construction steps of the input device 400A. The cross-sectional configuration shown in Fig. 13 and Fig. 14 corresponds to a cross-sectional view taken along the line A-A' shown in Fig. 11. First, as shown in Fig. 13 (a), a covering member 45 having a housing portion 45a and a panel supporting portion 45 A is prepared. When the covering member 45 is made of a resin material, it is possible to easily manufacture the accommodating portion 45a and the panel supporting portion 45A by injection molding. Further, if it is made of a metal material, the accommodating portion 45a and the panel supporting portion 45A can be manufactured by cutting or press working. When the covering member 45 is prepared, the separately formed touch panel 4 and the main surface 4s of the input operation surface are fitted into the accommodating portion 45a from the opening end side of the accommodating portion 45a on the side opposite to the panel supporting portion CA. As the touch panel 4, a conventional manufacturing method can be applied to the manufacturing method thereof by using a conventionally constructed constructor. When the touch panel 4 is fitted into the accommodating portion 45a, as shown in FIG. 13(b), the opening portion 45b of the panel supporting portion 45A is narrower than the main surface 4s of the touch panel 4, so that the main surface of the touch panel 4 is The touch panel 4 is housed in the accommodating portion 45a in a state where 4s is in contact with the back surface 45c of the panel supporting portion 45A. At this time, if an adhesive is provided between the back surface 4SC of the panel supporting portion 45A and the main surface 4 s of the touch panel 4, the touch panel 4 can be embedded only in the receiving portion 45a, and the corresponding strength can be fixed. Touch panel 4. Then, as shown in Fig. 13 (b), the back side film member 31 made of, for example, a PET film is bonded to the back side substrate 8b of the touch panel 4 across the cover member 45. For the adhesion of the back side film member 31, for example, a resin-based adhesive can be used. Thereby, the touch panel 4 housed in the accommodating portion 45a is fixed to the cover by the back side film member 31 attached to the back side (the side opposite to the panel supporting portion 455A) Member 4 5. Next, as shown in Fig. 13 (c), a film member 30 made of, for example, a PET film is prepared. The light shielding film 46 is printed on the surface of the film member 30 which is the side of the covering member 45. Then, as shown in Fig. 13 (d), the film member 30 is disposed so as to cover the cover member 45 and the touch panel 4 with the printing surface facing the cover member 45 side. At this time, the opening 46a of the light shielding film 46 on the surface of the film member 30 is aligned so that the opening 46a of the light shielding film 46 is disposed in the opening 45b of the panel supporting portion 45A. Next, as shown in Fig. 14 (a), the film member 30 is heated by the heating means 3 5 to soften the film member 30, and the film member 3 is thermally fused to the touch panel 4 and the covering member 45. As such a melting method, a fusion method such as hot plate melting, vacuum heat sealing, vibration melting, ultrasonic welding, laser melting, impact melting, high frequency induction heating, electromagnetic induction heating, and hot press melting can be used. As a result, as shown in FIG. 14 (b), the softened film member 3 〇 enters the opening 45b of the panel supporting portion 45A to be along the main surface of the touch panel 4 -49-200903074 4s, and touch The step of the panel 4 and the cover member 45 is connected to the touch panel 4 and the cover member 45. Further, by this step, the step portion 43 which follows the shape of the step of the touch panel 4 and the covering member 45 is formed on the surface of the thin member 30. As described above, according to the manufacturing method of the present embodiment, since the heat-dissipating film member 30 closes the step of the touch panel 4 and the cover member 45 of the touch panel 4, the touch panel 4 and the cover are covered. The step of the member can be relaxed by the film member 30, and the input device 40A for the degree of freedom in designing the cartridge can be easily prepared. Further, the panel is embedded in the accommodating portion 45a of the cover member 45, and the back side film member 3 1 ' is adhered and fixed by the back side of the touch panel 4, so that the touch panel 4 can be fixedly covered in an extremely simple procedure. Member 45. Further, when the light-shielding film 46 or the like is printed on the surface of the film member 30, the film member 30 cannot be bonded to the film member 3 when it is thermally melted, and the film member 3 corresponding to the formation region of the light-shielding film 46 is formed. 0 Surface, or an adhesive may be disposed on the surface of the covering member 45. [Second Configuration Example] The input device 40B according to the second configuration example shown in Fig. 1 (b) is filled between the wall portions of the accommodating portion 45a between the touch panel 4 and the cover member 45. The adhesive 42 is in a planar frame shape surrounding the touch panel 4. That is, the touch panel 4 is fixed to both the film member 3 and the cover member 45. The dense film is made of 4 5 thinner than the force of the inner cover 50-200903074 Next, according to the input device 4 0 between the touch panel 4 and the cover member 45 is provided with the adhesive 4 2 B, in addition to the same operational effects as those of the input device 40A described above, the following effects can be obtained. First, the touch panel 4 is fixed to the covering member 45 by the adhesive agent 4 2, and the back side film member 31 of the first configuration example becomes unnecessary. Therefore, for example, a display means such as a liquid crystal panel is provided on the back side of the touch panel 4, and when the display is transmitted through the touch panel 4, light loss when passing through the back side film member 31 or surface of the back side film member 31 The reflection does not occur anymore, resulting in a bright display. In addition, the movement of the touch panel 4 in either of the substrate surface direction and the substrate thickness direction is restricted, so that the touch panel 4 can be prevented from being pressed deep into the depth due to the input operation of the touch panel 4, or The touch panel 4 is moved in the accommodating portion 45a due to the impact of the drop, so that it can be an input device excellent in operability and durability. The input device 40B according to the second configuration example can be manufactured in the same manner as the input device 40A of the first configuration example described with reference to Figs. 13 and 14 . However, since the input device 40B does not require the back side film member 3 1, it is provided in the contact disposed in the accommodating portion 45a instead of the step of bonding the back side film member 31 shown in Fig. 13(b). The step of disposing the adhesive agent 4 between the control panel 4 and the inner wall of the accommodating portion 45 a may be performed. In this case, the adhesive 42 can be applied to the specific position by the applicator or the like after the touch panel 4 is housed in the accommodating portion 45a. However, the adhesive 42 is applied to the touch contained in the accommodating portion 45a in advance. The side portion of the panel 4 may also be used. -51 - 200903074 Alternatively, the adhesive 42 may be applied to the inner wall surface of the accommodating portion 45a. [Third configuration example] Fig. 15 is a schematic cross-sectional view showing an input device 40C of a third configuration example of the input device of the third embodiment. Fig. 15 is a view corresponding to Fig. 1 (a) of the first configuration example. The input device 40C of the present example is different from the input device 40B of the second configuration example in that the film member 130 formed by the cover member 45 and the touch panel 4 is provided with the first resin layer 131 and the second layer. This is the constitution of the resin layer 143. In the first embodiment, the same components as those in FIG. 10 are denoted by the same reference numerals, and detailed description thereof will be omitted. As shown in FIG. 15, the film member 130 includes a first resin layer 1 having a planar shape of a main surface 45a of the cover member 45 and a main surface 4s of the touch panel 4 exposed from the opening 45b of the panel support portion 45A. 3 1, the second resin layer 133 formed on the surface opposite to the covering member 45 of the first resin layer 133. In the first resin layer 131, similarly to the film member 30 of the single-layer structure of the first configuration example and the second configuration example, polyethylene (polyethylene) such as PET (polyethylene terephthalate) or polyester can be used. A film material composed of a transparent resin material such as polypropylene. As shown in FIG. 15, the second resin layer 133 is partially formed on the first resin layer 133, and is formed in a substantially rectangular frame shape in plan view similar to the light-shielding film 46, and is overlapped with the light-shielding film 46. . The second resin layer 132 has a surface 132a corresponding to the opening 46a of the light shielding film 46. The opening 132a corresponding to the rectangular opening portion 132a is formed inside the portion 46a of the light shielding film 46. The first resin layer 133 on the lower layer side is placed in the opening 132a of the second resin layer 132. The second resin layer 13 2 is formed using a resin material having a lower hardness (higher flexibility) than the material constituting the first resin layer 133. In the case where the first resin layer 133 is a PET film, the second resin layer is formed using polyethylene, polyurethane, acryl or the like. In the input device 40C of the present embodiment having the above-described configuration, the film 130 is a film member 30 having a two-layer structure of the first resin layer 131 and the second resin layer 132, and is thermally fused to the touch panel 4 and the cover 45. When the second resin layer 133 formed by using a resin having a lower hardness than the first resin layer 133 is softened and expanded, the film of the step of the touch portion 4 and the edge portion of the covering member 45 is formed. The structure of the member 1 30 is good, and the adhesion to the film member 130 and the touch panel 4 and the cover 45 can be improved. This makes it possible to achieve an excellent input device with both reliability and new style. Further, since the first resin layer 133 is relatively exposed on the touch panel 4 in the input device 40C, it is possible to prevent the input device 3 or the finger from sliding when the coordinate input operation is performed on the touch panel 4. Abrasion due to handling or scratching of the cover member 45 or the surface of the touch panel. As the first resin layer 133, it is preferable to prevent the above-mentioned abrasion or scratching well, or to obtain a good PET transparent film. Open the opening, exposed resin such as, 132 components. In the present example, the second resin layer is formed in a substantially rectangular frame shape which almost overlaps with the plan view of the light shielding film 46 in the plan view. In the case of 1 3 2, the purpose of providing the second resin layer 1 32 is to closely contact the film member 130 along the step formed at the boundary portion between the touch panel 4 and the covering member 45. Therefore, in this example, In other cases, the desired purpose can be achieved by providing at least a boundary portion between the touch panel 4 and the cover member 45. Further, the second resin layer 132 is not limited to the boundary portion between the touch panel 4 and the cover member 45, and may be disposed in a region where other steps are formed. For example, when the main surface 45s of the covering member 45 is formed with a projection or a recess, if the second resin layer 133 is selectively formed at a position overlapping the projection or the recess in a plan view plane, the projection or the recess may be formed. The portion of the film member 130 is well adhered. Further, in this example, the configuration of the film member 1 30 that adheres to the two-layer structure will be described. However, instead of the film member 130, a film member in which three or more layers of the resin layer are laminated may be provided. By using a film member in which a plurality of resin layers having different hardnesses are arranged in a selective plane, the adhesion at the time of melting (following the unevenness) can be highly controlled, and the reliability and newness of the input device can be improved. Further, instead of the film member 130, a film member having a structure in which a resin film having a different hardness is formed in a planar region may be used. For example, a PET film having a rectangular shape in plan view corresponding to the main surface 4s of the touch panel 4 and a polyethylene film disposed so as to surround the PET film in a plan view plane may be used. Partially integrated film member. -54 - 200903074 <Manufacturing Method of Input Device According to Third Configuration Example> Next, a method of manufacturing the input device 40C according to the third configuration example will be described with reference to Fig. 16 . Figure 16 is a schematic cross-sectional view showing the construction steps of the input device 40C. The cross-sectional configuration shown in Fig. 16 corresponds to a cross-sectional configuration along the position of the A - A ' line which is not shown in Fig. 11. First, as shown in FIG. 16(a), the cover member 45 having the accommodating portion 45a and the panel supporting portion 45A is prepared, and the separately manufactured touch panel 4 is input to the main surface 4s of the operation surface from the panel supporting portion 4 to be formed. The open end side of the accommodating portion 455 a on the opposite side of the 5 A is fitted into the accommodating portion 45a. Thereafter, the back side film member 31 made of, for example, a PET film is bonded to the back side substrate 8b of the touch panel 4 across the cover member 45. Further, as shown in Fig. 16 (a), a film member 130 obtained by laminating, for example, a first resin layer 133 made of a PET film and a second resin layer 132 made of a polyethylene film is prepared. The light shielding film 46 is printed on the surface of the film member 30 on the side of the covering member 45. Then, as shown in Fig. 16 (b), the film member 130 is disposed so as to cover the cover member 45 and the touch panel 4 with the printing surface facing the cover member 45 side. At this time, the opening 46a of the light shielding film 46 on the surface of the film member 130 is aligned so that the opening 46a of the light shielding film 46 is disposed in the opening 45b of the panel supporting portion 45A. Next, as shown in Fig. 16 (c), the film member 130 is heated by the heating means 315 to soften the film member 130, and the film member 130 is thermally dissolved on the touch panel 4 and the covering member 45. As such a fusion method, -55-200903074 can be melted by hot plate, vacuum heat fusion, vibration fusion, ultrasonic fusion, laser fusion, impact fusion, high frequency induction heating, electromagnetic induction heating, hot melt bonding, etc. method. As a result, as shown in FIG. 16(d), the softened film member 130 enters the opening portion 45b of the panel supporting portion 45A, along the main surface 4s of the touch panel 4, and the touch. The step of the panel 4 and the cover member 45 is in close contact with the touch panel 4 and the cover member 45. Further, by this step, the step portion 43 of the shape following the step of the touch panel 4 and the covering member 45 is formed on the surface of the film member 130. In the present embodiment, since the second resin layer 133 composed of a resin material having a low hardness is formed on the first resin layer 133 of the film member 130, heating by the heating device 350 is performed. The second resin layer 133 having high flexibility is spread over the first resin layer 133. Thereby, the film member 130 is smoothly adhered to the step of the touch panel 4 and the covering member 45. As described above, according to the manufacturing method of the present embodiment, since the film member 130 of the two-layer structure is thermally fused, the step of the touch panel 4 and the touch panel 4 and the cover member 45 are closely contacted, so The step of the control panel 4 and the covering member 45 can smoothly close the film member 130 to the step of the touch panel 4 and the covering member 45. Therefore, the above-described step difference can be effectively alleviated, and the input device 40C which improves the degree of design freedom can be manufactured in a simple procedure. Further, the panel 4 is fitted in the accommodating portion 45a provided in the covering member 45, and the back side of the touch panel 4 is bonded and fixed to the back side thin-56-200903074 film member 3 1, so that it can be extremely simple The step of fixing the touch panel 4 to the cover member 45. [Fourth and fifth configuration examples] Next, Fig. 17 (a) is a schematic cross-sectional view of the input device 40D of the fourth configuration example of the input device of the third embodiment. Fig. 17 (b) is also a schematic cross-sectional view of the input device 40E of the fifth embodiment. Fig. 17 (a) and Fig. 17 (b) correspond to Fig. 10 (a) of the first configuration example. In the input device 40D of the fourth configuration example, the input device 40A of the first configuration example is basically configured, and the film member 30 formed by the cover member 45 and the touch panel 4 is formed with the opening portion 30a. It is different. Further, the input device 40E of the fifth configuration example is basically configured by the input device 40C of the third configuration example, and the film member 1 30 formed by the cover member 45 and the touch panel 4 is formed with the opening portion 1 3 0a. This is different. In other words, the same components as those in FIG. 10 and FIG. 15 are denoted by the same reference numerals, and detailed description thereof will be omitted. As shown in Fig. 17 (a), the opening portion 30a of the film member 30 of the input device 4A of the fourth configuration example is along the light shielding film 46 which is formed to overlap the peripheral portion of the touch panel 4. The end edge of the opening portion 46a is formed in a rectangular shape, and is opened corresponding to a planar region that becomes an input operation portion of the touch panel 4. Further, as shown in FIG. 17(b), the opening portion 130a of the film member 130 of the input device 40E according to the fifth configuration example is also stacked on the peripheral portion of the touch panel 4 with a weight of -57-200903074. The end edge of the opening portion 46a of the formed light shielding film 46 is formed in a rectangular shape, and is opened corresponding to a planar region which becomes an input operation portion of the touch panel 4. That is, the input device 40D, 40E' causes the input device 3 or the finger to slide directly on the front side substrate 8a to perform an input operation to the touch panel 4. The input devices 4A and 40E having the fourth and fifth configuration examples of the above-described configuration perform an input operation to the touch panel 4 by directly pressing the front substrate, thereby performing an input operation with the transparent film member 30. The input device 40A of the first configuration example and the input device 40C of the third configuration example in which the input operation is performed by the film member 130 are lower than the operation pressure, and an appropriate input operation can be performed. Further, in the fourth and fifth configuration examples, the film member 30 and the film member 130 are partially removed to form the openings 30a and 130a. Therefore, the area where the film member 30 or the film member 130 and the touch panel 4 are bonded is only the touch. The peripheral region of the panel 4 (front side substrate 8a) is only used. The width of the peripheral region varies depending on the size of the touch panel 4, but it is usually at least a few mm, so that the bonding strength of the film member 30 or the film member 130 to the touch panel 4 can be ensured. However, when the input devices 40 A and 40C of the prior art example are compared, the bonding area is narrow and the bonding strength is low. Therefore, the input devices 40D and 40E of the fourth and fifth configuration examples are related to the second configuration example. Similarly, the input device 40B is preferably provided with an adhesive 42 disposed between the touch panel 4 and the cover member 45 to adhere the cover member 45 and the touch panel 4. Further, in the case of the fourth and fifth configuration examples, as shown in Fig. 17, the light shielding film 46 formed on the side of the covering member 45 of the film member 30 or the film member 130 is formed in It is preferable that the outer side of the opening 30a of the film member 30 and the outer side of the opening 1130a of the film member 130 are not exposed to the openings 30a and 130a. With such a configuration, peeling of the interface between the light shielding film 46 and the film members 30, 130 can be prevented, and the light shielding film 46 can be effectively protected. Further, in the fourth and fifth configuration examples, since the front surface side substrate 8a of the touch panel 4 is exposed, the substrate main body 11a of the front side substrate 8a is dropped, etc., if it is a glass substrate. When the glass substrate is damaged by the impact, the fragment will be scattered around. In other words, in the case of the configuration shown in this embodiment, the substrate body 11a as the front side substrate 8a is preferably a high-strength glass substrate or a plastic substrate. Alternatively, it is preferable to form a protective layer by coating a transparent resin or the like on the surface of the substrate main body 11a. [Fourth embodiment] Next, a photovoltaic device according to a fourth embodiment of the present invention will be described with reference to Fig. 18.
