201145112 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種可透過自液晶面板等發出之顯示光之 操作裝置，特別是關於一種可提高外光之反射的防止功 能，且可補正由顯示光透過各層所引起的色彩變化之操作 裝置。 ' 【先前技術】 攜帶用機器等之各種電子機器，係於液晶顯示面板等之 顯示面板的表面設置有透光性的操作面板。操作面板係使 具有特定的電阻值之透光性的導電層隔以空隙而對向，並 在利用押壓操作力使導電層彼此接觸之時，可由電阻的變 化檢測其接觸位置之觸控面板。或是，使彼此交又之朝向 的透光性之電極對向，在手指等之導電體接近之時，可檢 測形成於電極與手指之間之靜電電容，而生成對應於操作 位置之信號之靜電電容型的觸控面板。 此種操作面板存在有外部之光容易由前述操作面板之内 部之層的邊界部等反射，而不易觀察到液晶面板的顯示内 容之問題。特別是如電阻式觸控面板般，若於内部介有空 隙’則光容易在空隙與電極之邊界部反射，且在外部之光 較強之時、或於使用者的背部存在有光源之時等，會極難 觀察到顯示内容。 於以下之專利文獻1與專利文獻2中記載之觸控面板可藉 由於層構造之内部設置λ/4相位差膜與偏光膜，並將來自 外4之光變換為直線偏光與圓偏光，而防止由觸控面板之 153089.doc 201145112 内部反射之外光再次透過觸控面板而返回。 但，因偏光膜係使PVA(聚乙烯醇）吸附碘或染料等並於 一方向延伸而形成者，故其自身具有帶黃之色調。因此， 自顯不面板發出之顯示光會藉由透過偏光膜，使利用色調 與彩度顯示之色度發生變化，而易於導致顯示品質下降。 於以下之專利文獻3中記載之觸控面板可設置λ/4波長板 與偏光板，而防止來自外部之光的反射，且於層構造之内 部設置折射率不同的3層以上之多層膜，並利用該多層 膜，抵消偏光板的黄色帶給液晶面板的顯示光之影響。 [先前技術文獻] [專利文獻] 專利文獻1·日本特開2000-105669號公報 專利文獻2 .日本特開2〇〇1_丨42644號公報 專利文獻3:曰本特開2〇〇 1-324707號公報 【發明内容】 [發明所欲解決之問題] 於專利文獻3中記載之觸控面板係藉由於内部設置折射 率不同之3層以上的多層膜，而將色溫的峰值波長設定在 550 nm以下，並將觸控面板的峰值波長朝帶藍之方向調 整’藉此而抵消偏光板之變黃的影響者。 但，多層膜需要嚴格管理各膜之取向率與膜厚下進行成 膜’以致製造步驟複雜且成本變高。又，雖必須將多層膜 的色溫之峰值波長設定在可抵消實際的偏光板之變黃之範 圍内’但此種設定較難’且有效抵消除偏光板的變黃較困 153089.doc 201145112 n 。，在多層臈中，即使可進行色調的調整，實際上亦 無法調整彩度等。再者，若將觸控面板的峰值波長朝帶藍 方向調整，則會導致大於550 nm之波長的光之透射率下 降’且液晶面板的顯示内容之亮度或明度會易於下降，而 易使顯示品質下降。 β本發明係為解決上述先前之問題而完成者，丨目的在於 提供一種可藉由使用包含例如顏料或是染料之色彩補正 層將又偏光層影響等之顯示色的變化就其色調及彩度兩 者予以調整之操作裝置。 又，本發明之目的在於提供一種在使用色彩補正層之情 形下，即使透過色彩補正層的内部之光發生漫反射或是擴 散，亦不易受到其影響之構造的操作裝置。 [解決問題之技術手段] 本發明之操作裝置之特徵為於透光性之基板上具有： λ/4相位差層、位於其上之透光性的下部導電層與上部導 電層對向之檢測部、位於其上之λ/4相位差層及位於其上 之偏光層；且 進行透過前述基板至前述偏光層之顯示光的色彩補正之 色彩補正層係配置於前述偏光層上。 例如，前述色彩補正層為包含顏料或是染料者。 因本發明之操作裝置於内部具有λ/4相位差層與偏光 層，故可利用直線偏光與圓偏光防止來自外部之入射光的 反射。又，因係利用色彩補正層補正由偏光層等之存在所 弓I起的色彩變化’故可調整色調及彩度兩者而進行色度的 153089.doc 201145112 補正。 因色彩補正層包含顏料或是染料，故光易於在其内部發 生漫反射或是擴散，且易於對直線偏光或圓偏光造成影 響。是以，藉由將色彩補正層配置於上部的偏光層之上 方，將使色彩補正層的漫反射或是擴散不會對顯示光的直 線偏光與圓偏光造成影響’且亦不會對來自外部之光的反 射防止功能造成不良影響。 本發明之前述檢測部具有介存於前述下部導電層與前述 上部導電層之間之空隙部，且可利用來自外部之操作力使 前述上部導電層與前述下部導電層接觸而獲得檢測輸出 者，尤其可發揮其有效性。 於内部具有空隙之檢測部雖易於反射來自外部之光，但 藉由設置λ/4相位差層與偏光層，即使來自外部之光在空 隙與下部導電層之邊界部發生反射，亦可防止反射光返 回。惟，本發明即使是於靜電電容型面板等内部為無空隙 之層構造亦可實施4該情形下，亦可容易地防止=板 的内部之層邊界處所引起的光之反射。又，檢測部亦可是 下部導電層與上部導電層接觸而切換⑽七即之開關面 板。 、本發明可構成為前述基板係設置於輸出直線偏光的顯示 ::: 頁不面板上’且顯示光的偏光之朝向與前述偏光層的 远過軸之朝向一致。 藉由如上所述之構成 光之顯示光之情形下， ’如同液晶面板等般在發出直線偏 可容易防止其顯示光在透過操作裝 153089.doc 201145112 置的各層之時之光的透過效率之下降。 本發明係宜於前述色彩補正層之更上方設置有自外部操 作之透光性的覆層，且前述色彩補正層係包含前述顏料或 是染料之黏著層或接著層，且包夾前述色彩補正層，使前 述偏光層以及前述覆層接合者。 藉由將色彩補正層兼作黏著層或是接著層，可減少操作 裝置的層構造，且容易實現薄型化。 又’前述覆層亦可為於其一部分設置有著色層者。在該 情形下，因色彩補正層係位於覆層的下方，且到達至覆層 之顯不光已被色彩補正’故覆層的著色層之色彩設計可與 色彩補正無關聯地作為標準色彩決定。 [發明之效果] 本發明之操作裝置可藉由利用直線偏光與圓偏光，而容 易地防止外部的光之反射。又，可就色調與彩度兩者之要 素補正由偏光層等之存在所引起的顯示光之色度的變化。 且，亦可抑制由色彩補正層的内部之漫反射所引起的影 響。 〃 【實施方式】 圖1所不之携带機器1係作為行動電話、攜帶用資訊處理 裝置、攜帶用記憶裝置及攜帶用遊戲裝置等被使用。 携带機器1具有合成樹脂製的外殼2。外殼2具有上方開 放之凹。卩3，且於凹部3的内部收納著安裝有電子電路之電 路基板。另，於凹部3的内部收納有液晶顯示面板％。凹 部3的開口部係由本發明之操作裝置的實施形態之操作面 153089.doc 201145112 板ίο塞住。 在圖2之剖面圖中，雖顯示液晶顯示面板3〇與操作面板 10上下分離’但在外殼2的内部，卻是液晶顯示面板30與 操作面板10彼此密接。 如圖2所示般’液晶顯示面板30於下部具有導光基板 3 1。導光基板3 1係由透明的透光性樹脂形成。透光性樹脂 係為PMMA(曱基丙烯酸曱酯樹脂）、PC(聚碳酸酯）及 COP(環狀烯烴共聚物）等。於外殼2的内部設置有led等光 源’且背光裝置係由導光基板3丨與光源構成。自光源發出 之光被引導至導光基板31的内部，且由導光基板31的底部 等漫反射而朝向上方。 本說明書中的「透光性」是意味著可透過透明或是半透 明等之光之狀態，且意味著總透光率為5〇%以上，較佳的 是80%以上之情形。 於導光基板31上設置有偏光膜32,且於其上固定有下部 電極基板33。導光基板31與偏光膜32係經由透光性的黏著 層被固定，偏光膜32與下部電極基板33亦是經由透光性的 黏著層被固定。於下部電極基板33之朝上的表面上設置有 下部電極34與配向膜35,再者，於其上方有上部電極基板 36對向，且於上部電極基板36之朝下的表面上設置有上部 電極37與配向膜38。^下部電極基板33與上部電極基板^ 且下部電極基板33與上部電極基板36係 之間介有間隔件， 於下部電極基板33與上部電極基板 以特定間隔對向。且， 36之間介有液晶層39。 153089.doc 201145112 下部電極基板33與上部電極基板36皆具有透光性，且係 由玻璃板或是透明之合成樹脂膜形成。下部電極34與上部 電極37係由ITO等形成的透明電極層。下部電極34與上部 電極37皆平行延伸，一方係在X方向上延伸，另一方係在 Y方向上延伸。 於上部電極基板36上設置有偏光膜41。上部電極基板36 與偏光膜41係經由透明的黏著層被固定。下側之偏光膜32 的吸收軸及透過軸的朝向與上側之偏光膜41的吸收軸及透 過轴的朝向係因應液晶層36的扭轉角而決定。 上部電極基板36係為彩色濾光片基板，且藉由控制對下 部電極34與上部電極37之交又部的像素之通電，而利用液 晶顯示面板30進行色彩顯示。自背光裝置的導光基板31發 出之光係藉由透過液晶顯示面板3〇，而朝上發出進行色彩 顯示且為直線偏光之顯示光。 操作面板10具有支持基板11。支持基板丨丨係由pMMA(甲 基丙烯酸甲酯樹脂）、PC(聚碳酸酯）&c〇p(環狀烯烴共聚 物）等之透光性樹脂形成。或是，支持基板u係為玻璃基 板。於支持基扳11上經由透光性的黏著層12接合有作為 λ/4相位差層之λ/4相位差膜13，且於λ/4相位差膜^之朝上 的表面上形成有ΙΤΟ等之透光性的下部導電層14。於其上 方設置有λ/4相位差膜15，於人/4相位差膜15之朝下的表面 上形成有ΙΤΟ等之透光性的上部導電層μ。 下側之λ/4相位差膜13與上側之λ/4相位差膜15係以介存 於周緣部之接著劑層17作為間隔件於上下隔以距離而對 153089.doc -]〇. 201145112 向，且於下部導電層14與上部導電層16之間形成有空隙 18 ° λ/4相位差膜係利用雙折射使入射之光分離為正交之2個 直線偏光成分，且賦予2個直線偏光成分1 /4波長的位相偏 差。若將λ/4相位差膜的光軸以相對於偏光膜的透過轴傾 斜45度或是135度之角度配置，則透過偏光膜之直線偏光 會通過λ/4相位差膜而變換為圓偏光，且該圓偏光會藉由 通過λ/4相位差膜，而返回至直線偏光。 如圖2所示般，於上側之λ/4相位差膜1 5的上側之表面經 由透光性的黏著層19重疊有作為偏光層之偏光膜21。設置 於操作面板10上之偏光膜21、及設置於液晶顯示面板3〇上 之前述偏光膜32、41係將吸附有碘或染料之聚乙烯醇 (PVA)樹脂之膜朝一方向延伸，且藉由以三乙酿乙酸酯 (TAC)的保護膜包夾其膜的兩面而構成。此種偏光膜21、 32、41雖具有透光性但色調會稍微帶黃。 設置於操作面板1〇上之偏光膜21與設置於液晶顯示面板 30的上側之偏光膜41其吸收軸與透過軸的朝向相同。 於偏光膜21的表面經由色彩補正層22固定有作為覆層之 覆蓋片23。色彩補正層22係以丙烯酸系的黏著劑為主體之 黏著層’直由色彩補正層22接合偏光膜21與覆蓋片23。藉 由以色形補正層為黏著層，可在不增加構成操作面板1〇之 層的數量下，附加色彩補正層。 本說明書中的黏著層及黏著劑係可利用自身的貼合力固 著2個膜者，且可與自液體其狀態硬化為固體之接著劑或 153089.doc 201145112 是接著層區別。惟’亦可將前述色彩補正層22及黏著層 12、19等之各種黏著層置換為前述接著層。 色彩補正層22包含顏料或是染料，利用色彩補正層22， 可補正自背光裝置的導光基板31發出，透過液晶顯示面板 30 ’且從操作面板1〇的支持基板丨丨至偏光膜21透過之顯示 光的色度偏差》 利用色彩補正層2 2之色度偏差補正係藉由顏料或是染料 的種類之選擇與其添加量的選擇而進行調整。 作為其調整方法之一例，代替具有導光基板31之背光而 使用標準光源’使標準光自液晶顯示面板3〇及操作面板1〇 的支持基板11至偏光膜21透過，並利用色度計測定所透過 之光的色度。將所測定之色度與標準光源之標準色的色度 應用於XYZ表色系之色度圖中。於色度圖上，求出用以補 正所測定之色度與標準色的色度之差之色調，進而求出用 以補正為標準色之彩度。因應所求出之補正用的色調選擇 顏料或是染料的色調’並將其添加至色彩補正層22中。 又，藉由變化於色彩補正層22中添加之顏料或是染料的 量’而進行包含彩度之色度的補正。 如此，藉由將色彩補正層22作為包含顏料或是染料之層 予以構成，可在色調與彩度兩者中嚴密地補正透過偏光膜 及其他各層之顯示光的色度偏差。 覆蓋片23係由聚對苯二甲酸乙二醇酯（pET)等之透明的 樹脂片形成。如圖1所示般’操作面板1〇係以中央之四角 區域為顯示區域10a，其周圍係被著色之框部丨〇b。如圖2 153089.doc 201145112 所般於覆蓋片23的朝下之表面形成有對應於前述框部 1〇b之著色層24。著色層24係利用印刷、塗裝或是濺射等 之手法形成°經由操作面板1 〇的顯示區域10a可目視液晶 顯示面板30的顯示内容。另一方面，框部1〇b係由著色層 24的色彩裝飾。 在圖2中，（A)係顯示自導光基板3 1發出’並透過液晶顯 不面板30與操作面板1〇之色彩顯示光的路徑，（B)係顯示 自外部入射至操作面板丨〇之外光的路徑。 在色彩顯示光之路徑（A)中，自導光基板3丨發出之照明 光（1)可藉由通過液晶顯示面板30的液晶層39與作為色彩濾 光片基板之上部電極基板36而成為色彩顯示光。經由液晶 顯示面板30之色彩顯示光係透過2個偏光膜32、41之直線 偏光（2)。 在操作面板10中’直線偏光（2)係藉由通過下側的λ/4相 位差膜13而成為圓偏光（3)，進而通過上側的λ/4相位差膜 15而返回至直線偏光（4)。因液晶顯示面板30的上側之偏光 膜41與操作面板1〇之偏光膜21係為透過軸的朝向相同，故 色彩顯示光可作為損失較少之直線偏光（5)朝上方供給。 在來自外部之光的路徑（Β)中，若外光（6)入射至操作面 板10 ’則會經由偏光膜21而成為直線偏光（7)，並透過上側 之λ/4相位差膜15而成為圓偏光（8)。若圓偏光（7)由上側之 λ/4相位差膜1 5與下側之λ/4相位差膜13之間的任意之層反 射，則會成為逆轉之圓偏光（9)而返回。該圓偏光（9)雖可 透過上側之λ/4相位差膜15而成為直線偏光（1〇)，但該直線 153089.doc 13 201145112 偏光（10)的光轴會與偏光膜21的透過軸相差90度，且反射 光會被偏光膜21吸收而避免返回至外部。 圖2所示之操作面板1〇雖容易由空隙18與下部導電層14 之邊界部反射外光’但因該反射光係由偏光膜21吸收，故 不會受外部之光的強度或操作者的背部之景色等左右，而 隻得谷易目視液晶顯示面板3〇的色彩顯示光。 遵循路徑（A)之色彩顯示光因透過3個偏光膜32、41、21 而偏黃，且因透過其他層，而導致色度自原本之色彩顯出 光偏差。如前述般’該色度偏差係由色彩補正層22補正。 色彩補正層22係於黏著劑的内部包含顏料或是染料者， 且藉由調整顏料或是染料的類別之選擇與其添加量，可補 正色彩顯示光的色調與彩度。反之，透過色彩補正層22之 光容易於其内部被漫反射或是擴散。透過液晶顯示面板30 的偏光膜41與操作面板10的偏光膜21之間之色彩顯示光係 為直線偏光或是圓偏光。因而，假如色彩補正層22係存在 於偏光臈41與偏光膜21之間，則由光的漫反射或擴散會導 致偏光奈亂。若色彩顯示光在到達偏光膜21之前偏光狀態 紊亂，則會導致透過偏光膜21之光量減少，色彩顯示光的 明度下降，且顯示對比度會下降。是以，在圖2所示之操 作面板10中，藉由將色彩補正層22相較於偏光膜21配置於 上側’可避免偏光膜41與偏光膜21之間的偏光受到由色彩 補正層所引起的漫反射或擴散之影響。 因在色彩顯示光透過色彩補正層22之時點，色彩補正已 結束，故透過覆蓋片23之色彩顯示光為無色度偏差之顯示 153089.doc •14- 201145112 品質優異之光。因此，可經由操作面板1〇的顯示區域 l〇a，進行高品質且由反射光所引起之影響較少的色彩顯 不。又，在框部i〇b，可無色度偏差地表現由著色層24顯 示之色彩裝飾。 惟，在本發明中，亦可於覆蓋片23中混入顏料或是染 料，而作為色彩補正層使其發揮功能。在該情形下，因框 部的裝飾色會與源自顏料或是染料之色混合，故需要 以可與源自顏料或是染料之色度抵消之方式設定構成框部 l〇b之著色層24的色度。 構成檢測部之下部導電層14與上部導電層16具有特定的 電阻。如圖5所示般’於下部導電層14之又方向的兩端設置 有由電阻率小於下部導電層14之銀膠等所形成之χ電極層 14a、14b。於上部電極層16之丫方向的兩端亦設置有電阻 率小於上部電極層16之Y電極層16a、16b。 在操作面板10的動作中對X電極層1牝與又電極層14b之 間施加電壓，並在與其不同之時機，對γ電極層16&與γ電 極層16b之間施加電壓。自上側之λ/4相位差膜。至覆蓋片 23皆具有可撓性，若以手指等按壓覆蓋片23的表面，則會 使上部導電層16與下部導電層14部分接觸。圖5中係以ρ表 示其接觸點。此時，自γ電極層16a、16b檢測對應於在X 方向分割下部導電層14之電阻值之電壓，且自χ電極層 14a、14b檢測對應於在γ方向分割上部導電層16之電阻值 之電壓。藉此，檢測ρ點之χ_γ座標上的位置。 圖3係顯示比較例1之操作面板11〇，圖4係顯示比較例2 153089.doc -15· 201145112 之操作面板210。於圖3與圖4所顯示之液晶顯示面板30的 構造係與圖2顯示之液晶顯示面板30相同。在比較例1之操 作面板110與比較例2之操作面板210中，對與圖2所示之操 作面板10相同之構成部分標注以同一符號，而省略其詳細 說明。

Field of the Invention The present invention relates to an operation device that can transmit light emitted from a liquid crystal panel or the like, and more particularly to a function for preventing reflection of external light, and can be corrected by An operating device that displays color changes caused by light passing through the layers. [Prior Art] Various electronic devices such as portable devices are provided with a translucent operation panel on the surface of a display panel such as a liquid crystal display panel. The operation panel is a touch panel in which a light-transmitting conductive layer having a specific resistance value is opposed to each other by a gap, and when a conductive layer is brought into contact with each other by a pressing force, a contact position of the contact position can be detected by a change in resistance. . Alternatively, the translucent electrodes facing each other are opposed to each other, and when the conductors of the fingers or the like are close to each other, the electrostatic capacitance formed between the electrodes and the fingers can be detected to generate a signal corresponding to the operation position. Capacitive touch panel. In such an operation panel, there is a problem that external light is easily reflected by a boundary portion or the like of the inner layer of the operation panel, and the display content of the liquid crystal panel is not easily observed. In particular, if a gap is formed inside, such as a resistive touch panel, light is easily reflected at the boundary between the gap and the electrode, and when the external light is strong, or when there is a light source on the back of the user. Wait, it will be extremely difficult to observe the display. The touch panel described in Patent Document 1 and Patent Document 2 below can be configured by arranging a λ/4 retardation film and a polarizing film inside the layer structure, and converting light from the outer 4 into linear polarized light and circularly polarized light. Prevents the light from being reflected by the internal touch of the touch panel 153089.doc 201145112 again through the touch panel. However, since the polarizing film is formed by adsorbing iodine, a dye, or the like in a direction in which PVA (polyvinyl alcohol) is formed, it has a yellowish hue. Therefore, the display light emitted from the panel is changed by the chromaticity of the hue and chroma display by the polarizing film, which tends to cause deterioration in display quality. The touch panel described in the following Patent Document 3 can be provided with a λ/4 wavelength plate and a polarizing plate to prevent reflection of light from the outside, and to provide a multilayer film having three or more layers having different refractive indices inside the layer structure. The multilayer film is used to offset the influence of the yellow light of the polarizing plate on the display light of the liquid crystal panel. [PRIOR ART DOCUMENT] [Patent Document 1] Japanese Laid-Open Patent Publication No. 2000-105669 (Patent Document 2) Japanese Patent Laid-Open Publication No. Hei No. Hei. In the touch panel described in Patent Document 3, the peak wavelength of the color temperature is set to 550 by providing a multilayer film of three or more layers having different refractive indices. Below nm, and the peak wavelength of the touch panel is adjusted toward the direction of the blue color, thereby offsetting the influence of the yellowing of the polarizing plate. However, the multilayer film requires strict management of the orientation ratio of each film and film formation at the film thickness, so that the manufacturing steps are complicated and the cost becomes high. Moreover, it is necessary to set the peak wavelength of the color temperature of the multilayer film to a range that can cancel the yellowing of the actual polarizing plate, but this setting is difficult and effectively eliminates the yellowing of the polarizing plate. 153089.doc 201145112 n . In a multi-layered cymbal, even if the color tone can be adjusted, the chroma cannot be adjusted. Furthermore, if the peak wavelength of the touch panel is adjusted toward the blue direction, the transmittance of light having a wavelength greater than 550 nm may decrease, and the brightness or brightness of the display content of the liquid crystal panel may be easily lowered, and the display may be easily displayed. The quality is declining. The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a color change and a chroma which can be changed by using a color correction layer containing, for example, a pigment or a dye, to influence the polarization layer. The operating device for both adjustments. Further, an object of the present invention is to provide an operation device which is less susceptible to the influence of light diffusing or diffusing through the inside of the color correction layer in the case where the color correction layer is used. [Technical means for solving the problem] The operating device of the present invention is characterized in that the light-transmitting substrate has: a λ/4 phase difference layer, and a light-transmitting lower conductive layer and an upper conductive layer opposite thereto a λ/4 retardation layer located thereon and a polarizing layer positioned thereon; and a color correction layer for color correction of display light transmitted through the substrate to the polarizing layer is disposed on the polarizing layer. For example, the color correction layer described above is a pigment or a dye. Since the operating device of the present invention has a λ/4 retardation layer and a polarizing layer therein, it is possible to prevent reflection of incident light from the outside by linearly polarized light and circularly polarized light. Further, since the color correction layer is used to correct the color change caused by the presence of the polarizing layer or the like, the chromaticity of 153089.doc 201145112 can be corrected by adjusting both the hue and the chroma. Since the color correction layer contains a pigment or a dye, light is easily diffused or diffused inside, and it is easy to affect linear or circularly polarized light. Therefore, by arranging the color correction layer above the upper polarizing layer, the diffuse reflection or diffusion of the color correction layer does not affect the linear and circular polarization of the display light' and does not affect the external The reflection of the light prevents adverse effects. The detecting portion of the present invention has a gap portion interposed between the lower conductive layer and the upper conductive layer, and the upper conductive layer and the lower conductive layer can be brought into contact with each other by an external operating force to obtain a detection output. In particular, its effectiveness can be achieved. The detecting portion having a gap inside is easy to reflect light from the outside. However, by providing the λ/4 retardation layer and the polarizing layer, even if light from the outside is reflected at the boundary between the gap and the lower conductive layer, reflection can be prevented. Light returns. However, in the present invention, even in the case of a layer structure having no voids inside the electrostatic capacitance type panel or the like, it is possible to easily prevent reflection of light caused by the layer boundary inside the panel. Further, the detecting portion may be configured such that the lower conductive layer is in contact with the upper conductive layer to switch (10) the switch panel. In the present invention, the substrate may be disposed on the display of the output linearly polarized light ::: the page is not on the panel ′ and the direction of the polarized light of the display light coincides with the direction of the far axis of the polarizing layer. In the case of the display light constituting the light as described above, it is easy to prevent the transmission efficiency of light when the display light is transmitted through the respective layers of the operation device 153089.doc 201145112 as in the case of a liquid crystal panel or the like. decline. Preferably, the present invention is provided with a light-transmissive coating layer which is externally operated from the outside of the color correction layer, and the color correction layer comprises an adhesive layer or an adhesive layer of the pigment or dye, and the color correction is included The layer is such that the polarizing layer and the coating layer are joined. By using the color correction layer as an adhesive layer or an adhesive layer, the layer structure of the operation device can be reduced, and the thickness can be easily reduced. Further, the above-mentioned coating layer may be one in which a colored layer is provided in a part thereof. In this case, since the color correction layer is located below the cladding layer and the visible light reaching the cladding has been corrected by color, the color design of the color layer of the cladding layer can be determined as a standard color irrespective of color correction. [Effect of the Invention] The operating device of the present invention can easily prevent reflection of external light by utilizing linearly polarized light and circularly polarized light. Further, the change in the chromaticity of the display light caused by the presence of the polarizing layer or the like can be corrected in terms of both the hue and the chroma. Moreover, the influence caused by the diffuse reflection inside the color correction layer can also be suppressed. [Embodiment] The portable device 1 shown in Fig. 1 is used as a mobile phone, a portable information processing device, a portable memory device, a portable game device, and the like.

The opening of the recess 3 is blocked by the operation surface 153089.doc 201145112 of the embodiment of the operating device of the present invention. In the cross-sectional view of Fig. 2, the liquid crystal display panel 3 is vertically separated from the operation panel 10, but inside the casing 2, the liquid crystal display panel 30 and the operation panel 10 are in close contact with each other. As shown in Fig. 2, the liquid crystal display panel 30 has a light guiding substrate 31 on the lower portion. The light guide substrate 31 is formed of a transparent light transmissive resin. The light-transmitting resin is PMMA (nonyl methacrylate resin), PC (polycarbonate), and COP (cyclic olefin copolymer). A light source such as a led light is provided inside the casing 2, and the backlight device is composed of a light guide substrate 3A and a light source. The light emitted from the light source is guided to the inside of the light guide substrate 31, and is diffused and reflected upward by the bottom of the light guide substrate 31 or the like. The term "transparency" as used in the present specification means a state in which light which is transparent or semi-transparent, and the like, and means that the total light transmittance is 5% or more, preferably 80% or more. A polarizing film 32 is provided on the light guiding substrate 31, and a lower electrode substrate 33 is fixed thereon. The light guide substrate 31 and the polarizing film 32 are fixed via a translucent adhesive layer, and the polarizing film 32 and the lower electrode substrate 33 are also fixed via a translucent adhesive layer. The lower electrode 34 and the alignment film 35 are provided on the upper surface of the lower electrode substrate 33, and the upper electrode substrate 36 is opposed to the upper electrode substrate 36, and the upper surface is provided on the lower surface of the upper electrode substrate 36. The electrode 37 and the alignment film 38. The lower electrode substrate 33 and the upper electrode substrate are interposed between the lower electrode substrate 33 and the upper electrode substrate 36, and the lower electrode substrate 33 and the upper electrode substrate are opposed to each other at a predetermined interval. Moreover, a liquid crystal layer 39 is interposed between 36. 153089.doc 201145112 Both the lower electrode substrate 33 and the upper electrode substrate 36 are translucent and formed of a glass plate or a transparent synthetic resin film. The lower electrode 34 and the upper electrode 37 are transparent electrode layers formed of ITO or the like. The lower electrode 34 and the upper electrode 37 extend in parallel, one of which extends in the X direction and the other of which extends in the Y direction. A polarizing film 41 is provided on the upper electrode substrate 36. The upper electrode substrate 36 and the polarizing film 41 are fixed via a transparent adhesive layer. The orientation of the absorption axis and the transmission axis of the lower polarizing film 32 and the direction of the absorption axis and the transmission axis of the upper polarizing film 41 are determined by the torsion angle of the liquid crystal layer 36. The upper electrode substrate 36 is a color filter substrate, and color display is performed by the liquid crystal display panel 30 by controlling energization of the pixels of the intersection of the lower electrode 34 and the upper electrode 37. The light emitted from the light guide substrate 31 of the backlight device is transmitted through the liquid crystal display panel 3, and is colored upward to emit display light for linear display. The operation panel 10 has a support substrate 11. The support substrate is formed of a light-transmitting resin such as pMMA (methyl methacrylate resin), PC (polycarbonate) & c〇p (cyclic olefin copolymer). Alternatively, the support substrate u is a glass substrate. A λ/4 retardation film 13 as a λ/4 retardation layer is bonded to the support substrate 11 via a light-transmitting adhesive layer 12, and a ruthenium is formed on the surface of the λ/4 retardation film. The light transmissive lower conductive layer 14 is equal to. A λ/4 retardation film 15 is provided on the upper surface thereof, and a light-transmitting upper conductive layer μ such as tantalum is formed on the surface of the human/4 retardation film 15 facing downward. The λ/4 retardation film 13 on the lower side and the λ/4 retardation film 15 on the upper side are separated by a distance between the upper and lower layers of the adhesive layer 17 which is interposed in the peripheral portion as a spacer. 153089.doc -] 〇. 201145112 The gap between the lower conductive layer 14 and the upper conductive layer 16 is formed by a gap of 18 ° λ / 4 retardation film by using birefringence to separate the incident light into two orthogonal linear polarization components, and giving two straight lines The phase deviation of the 1/4 wavelength of the polarized component. When the optical axis of the λ/4 retardation film is disposed at an angle of 45 degrees or 135 degrees with respect to the transmission axis of the polarizing film, the linearly polarized light transmitted through the polarizing film is converted into circularly polarized light by the λ/4 retardation film. And the circularly polarized light is returned to the linearly polarized light by passing through the λ/4 retardation film. As shown in Fig. 2, a polarizing film 21 as a polarizing layer is superposed on the surface of the upper side of the upper λ/4 retardation film 15 via a light-transmitting adhesive layer 19. The polarizing film 21 provided on the operation panel 10 and the polarizing films 32 and 41 provided on the liquid crystal display panel 3 extend the film of polyvinyl alcohol (PVA) resin adsorbed with iodine or dye in one direction, and It is composed of a double-layered acetate (TAC) protective film sandwiching both sides of the film. Such polarizing films 21, 32, and 41 have a light transmittance but a slight yellowish hue. The polarizing film 21 provided on the operation panel 1 and the polarizing film 41 provided on the upper side of the liquid crystal display panel 30 have the same absorption axis and the transmission axis. A cover sheet 23 as a coating layer is fixed to the surface of the polarizing film 21 via the color correction layer 22. The color correction layer 22 is an adhesive layer mainly composed of an acrylic adhesive, and the polarizing film 21 and the cover sheet 23 are bonded directly by the color correction layer 22. By using the color correction layer as the adhesive layer, the color correction layer can be added without increasing the number of layers constituting the operation panel. The adhesive layer and the adhesive in the present specification can be fixed to the two films by their own bonding force, and can be distinguished from the adhesive which is hardened into a solid from the liquid state or 153089.doc 201145112. However, various adhesive layers such as the color correction layer 22 and the adhesive layers 12 and 19 may be replaced by the adhesive layer. The color correction layer 22 includes a pigment or a dye, and the color correction layer 22 can be corrected to be emitted from the light guide substrate 31 of the backlight device, transmitted through the liquid crystal display panel 30', and transmitted from the support substrate 操作 of the operation panel 1 to the polarizing film 21 The chromaticity deviation of the display light" The chromaticity deviation correction by the color correction layer 2 2 is adjusted by the selection of the type of the pigment or the dye and the selection of the added amount thereof. As an example of the adjustment method, a standard light source is used instead of the backlight having the light guide substrate 31 to transmit standard light from the support substrate 11 of the liquid crystal display panel 3 and the operation panel 1 to the polarizing film 21, and is measured by a colorimeter. The chromaticity of the light that is transmitted. The measured chromaticity and the chromaticity of the standard color of the standard light source are applied to the chromaticity diagram of the XYZ color system. On the chromaticity diagram, the color tone for correcting the difference between the measured chromaticity and the chromaticity of the standard color is obtained, and the chroma for correcting the standard color is obtained. The color tone of the pigment or dye is selected in accordance with the tone to be corrected for the correction and added to the color correction layer 22. Further, the correction including the chroma of the chroma is performed by changing the amount of the pigment or the dye added to the color correction layer 22. By configuring the color correction layer 22 as a layer containing a pigment or a dye as described above, it is possible to closely correct the chromaticity deviation of the display light transmitted through the polarizing film and the other layers in both the hue and the chroma. The cover sheet 23 is formed of a transparent resin sheet such as polyethylene terephthalate (pET). As shown in Fig. 1, the operation panel 1 has a central four-corner area as a display area 10a, and is surrounded by a colored frame portion 丨〇b. The coloring layer 24 corresponding to the aforementioned frame portion 1b is formed on the downward facing surface of the cover sheet 23 as shown in Fig. 2 153089.doc 201145112. The colored layer 24 is formed by a method such as printing, painting, or sputtering. The display content of the liquid crystal display panel 30 can be visually observed via the display area 10a of the operation panel 1A. On the other hand, the frame portion 1b is decorated by the color of the color layer 24. In Fig. 2, (A) shows a path in which the color light is emitted from the light guide substrate 31 and transmitted through the liquid crystal display panel 30 and the operation panel 1b, and (B) is displayed from the outside to the operation panel. The path of light outside. In the color display light path (A), the illumination light (1) emitted from the light guide substrate 3 can be obtained by passing through the liquid crystal layer 39 of the liquid crystal display panel 30 and the upper electrode substrate 36 as the color filter substrate. The color shows light. The color display light passing through the liquid crystal display panel 30 transmits the linear polarized light (2) of the two polarizing films 32 and 41. In the operation panel 10, the linearly polarized light (2) is converted into circularly polarized light (3) by passing through the lower λ/4 retardation film 13, and is returned to linearly polarized light by the upper λ/4 retardation film 15 ( 4). Since the polarizing film 41 on the upper side of the liquid crystal display panel 30 and the polarizing film 21 on the operation panel 1 are oriented in the same direction of the transmission axis, the color display light can be supplied upward as linearly polarized light (5) having less loss. In the path (Β) from the outside light, when the external light (6) is incident on the operation panel 10', it becomes linearly polarized (7) via the polarizing film 21, and passes through the upper λ/4 retardation film 15 Become a circular polarized light (8). When the circularly polarized light (7) is reflected by any layer between the upper λ/4 retardation film 15 and the lower λ/4 retardation film 13, the reversed circularly polarized light (9) is returned. The circularly polarized light (9) is linearly polarized (1 〇) through the upper λ/4 retardation film 15, but the optical axis of the polarized light (10) and the transmission axis of the polarizing film 21 are 153089.doc 13 201145112 The difference is 90 degrees, and the reflected light is absorbed by the polarizing film 21 to avoid returning to the outside. The operation panel 1 shown in FIG. 2 is easy to reflect external light by the boundary portion between the gap 18 and the lower conductive layer 14 but is not absorbed by the intensity of the external light or the operator because the reflected light is absorbed by the polarizing film 21. The scenery of the back is waiting for the left and right, and only the color of the liquid crystal display panel is displayed. The color following the path (A) indicates that the light is yellowish by the three polarizing films 32, 41, and 21, and the chromaticity is deviated from the original color due to the transmission of the other layers. The chromaticity deviation is corrected by the color correction layer 22 as described above. The color correction layer 22 is a pigment or a dye contained in the inside of the adhesive, and the color tone and chroma of the color display light can be corrected by adjusting the selection of the type of the pigment or the dye and the amount of the dye. Conversely, the light passing through the color correction layer 22 is easily diffused or diffused inside. The color display light transmitted between the polarizing film 41 of the liquid crystal display panel 30 and the polarizing film 21 of the operation panel 10 is linearly polarized or circularly polarized. Therefore, if the color correction layer 22 is present between the polarizing aperture 41 and the polarizing film 21, the diffuse reflection or diffusion of light causes a polarized light. If the color display light is disordered in the polarized state before reaching the polarizing film 21, the amount of light transmitted through the polarizing film 21 is reduced, the brightness of the color display light is lowered, and the display contrast is lowered. Therefore, in the operation panel 10 shown in FIG. 2, by arranging the color correction layer 22 on the upper side with respect to the polarizing film 21, it is possible to prevent the polarization between the polarizing film 41 and the polarizing film 21 from being received by the color correction layer. The effect of diffuse reflection or diffusion. Since the color correction is completed when the color display light passes through the color correction layer 22, the color display light transmitted through the cover sheet 23 is displayed without chromaticity deviation 153089.doc •14- 201145112 Excellent quality light. Therefore, color display with high quality and less influence by reflected light can be performed via the display area l〇a of the operation panel 1〇. Further, in the frame portion i〇b, the color decoration displayed by the color layer 24 can be expressed without chromaticity deviation. However, in the present invention, a pigment or a dye may be mixed in the cover sheet 23 to function as a color correction layer. In this case, since the decorative color of the frame portion is mixed with the color derived from the pigment or the dye, it is necessary to set the color layer constituting the frame portion l〇b in such a manner as to cancel the chromaticity derived from the pigment or the dye. The color of 24. The conductive layer 14 and the upper conductive layer 16 which constitute the lower portion of the detecting portion have a specific electric resistance. As shown in Fig. 5, tantalum electrode layers 14a, 14b formed of silver paste or the like having a lower specific resistance than the lower conductive layer 14 are provided at both ends in the other direction of the lower conductive layer 14. Y electrode layers 16a and 16b having a lower specific resistance than the upper electrode layer 16 are also provided at both ends of the upper electrode layer 16 in the meandering direction. A voltage is applied between the X electrode layer 1A and the further electrode layer 14b in the operation of the operation panel 10, and a voltage is applied between the γ electrode layer 16& and the γ electrode layer 16b at a timing different therefrom. λ/4 retardation film from the upper side. Each of the cover sheets 23 has flexibility. When the surface of the cover sheet 23 is pressed by a finger or the like, the upper conductive layer 16 is partially in contact with the lower conductive layer 14. In Fig. 5, the contact point is indicated by ρ. At this time, a voltage corresponding to the resistance value of dividing the lower conductive layer 14 in the X direction is detected from the γ electrode layers 16a, 16b, and the resistance value corresponding to the division of the upper conductive layer 16 in the γ direction is detected from the χ electrode layers 14a, 14b. Voltage. Thereby, the position on the χ γ coordinate of the p point is detected. 3 shows an operation panel 11A of Comparative Example 1, and FIG. 4 shows an operation panel 210 of Comparative Example 2 153089.doc -15·201145112. The structure of the liquid crystal display panel 30 shown in Figs. 3 and 4 is the same as that of the liquid crystal display panel 30 shown in Fig. 2. In the operation panel 210 of the comparative example 1 and the operation panel 210 of the comparative example 2, the same components as those of the operation panel 10 shown in Fig. 2 are denoted by the same reference numerals, and detailed description thereof will be omitted. The operation panel 11 of Comparative Example 1 shown in Fig. 3 has an adhesive layer 122 between the polarizing film 21 and the cover sheet 23 which does not contain a pigment or a dye, and does not have a function of a color correction layer. Instead, a pigment or a dye is mixed into the support substrate 111 of the operation panel 110, so that the support substrate 1 has a function as a color correction layer. The operation panel 210 of Comparative Example 2 shown in Fig. 4 is the same as the operation panel 110, and the adhesive layer 122 between the polarizing film 21 and the cover sheet 23 does not contain a pigment or a dye, and does not have the function of a color correction layer. Further, the support substrate 11 does not contain a pigment or a dye, and does not function as a color correction layer. Alternatively, the adhesive layer 219 between the upper side λ/4 retardation film 15 and the polarizing film 21 contains a pigment or a dye, and the adhesive layer 219 can function as a color correction layer. Table 1 below shows the results of comparing the functions of the operation panel 10 of the embodiment shown in Fig. 2, the operation panel 110 of Comparative Example 1 shown in Fig. 3, and the operation panel 210 of Comparative Example 2 shown in Fig. 4. The operation panel 1 and the operation panels 110 and 210 of the comparative example each use a color correction layer containing a pigment or a dye. The color correction layer can substantially adjust the chromaticity by adjusting the type of the pigment or the dye and its content. The operation panel 110 of Comparative Example 1 functions as a color correction layer. 153089.doc • 16- 201145112 The holding substrate 111 is located between the polarizing film 41 and the λ/4 retardation film 13. Therefore, the polarized state of the color display light which is linearly polarized by the polarizing film 41 is diffused or diffused inside the supporting substrate 111. Therefore, a disorder occurs in the linearly polarized light passing through the λ/4 retardation film 13 and the linearly polarized light passing through the λ/4 retardation film 15 on the upper side. Therefore, the amount of light transmitted through the polarizing film 21 on the upper side is lowered, and the contrast of the color display is lowered. The adhesive layer 219 functioning as a color correction layer of the operation panel 210 of Comparative Example 2 is located between the upper λ/4 retardation film 15 and the polarizing film 21. Therefore, the linearly polarized light of the color display light transmitted through the upper λ/4 retardation film 15 is diffusely reflected or diffused, and the amount of light transmitted through the upper polarizing film 21 is lowered, and the contrast of the color display is lowered. Further, the light from the outside of the operation panel 210 of Comparative Example 2, which is incident on the operation panel 210 via the cover sheet 23, is linearly polarized by the polarizing film 21, and is inside the adhesive layer 219 containing a pigment or a dye. Diffuse or diffuse. Further, the circularly polarized light reflected by the boundary portion between the gap 18 and the lower conductive layer 14 is diffused or diffused in the adherend layer 219 after being linearly polarized by the χ/4 retardation film 15. Therefore, the linearly polarized light of the reflected light includes a component that faces the transmission axis of the polarizing film 21, and the effect of preventing the reflection of the external light is lowered. Furthermore, the operation panel 110 shown in FIG. 3 has a color correction layer 22' manufacturing cost for the adhesive layer containing the pigment or dye as shown in FIG. 2 because the support substrate lu contains a pigment or a dye. Will increase. In Table 1 below, the respective disadvantage items of Comparative Example 1 and Comparative Example 2 are indicated by "X". 153089.doc -17- 201145112 [Table 1J —., ~~ΙΙΖΙ?^ ~ Contrast — 反 ΐ ΐ~~I~~~ 形态 形态 | | 〇 〇 〇 Comparative Example 1 〇 Comparative Example ^ 1 η-- _^_ tin In the operation panel 1 则, the lower conductive layer 14 and the upper portion are formed as the detecting portion.
