Description of the invention [Technical field to which the invention belongs] The present invention relates to a display panel assembly of a liquid crystal panel or the like, in which a light-curable sealant is used to attach two light-transmissive substrates to a display panel.合 装置。 The device. [Prior art] Generally, a liquid crystal screen is composed of a liquid crystal panel, a driver for controlling the liquid crystal panel, and a backlight that illuminates the liquid crystal panel from the back. The liquid crystal panel displays a picture by encapsulating liquid crystal and controlling the voltage applied thereto so that light from the backlight is transmitted or cut off. Fig. 6 is a cross-sectional view showing an example of a liquid crystal panel (color liquid crystal panel). In the same figure, 101 is a color filter substrate, 102 is a TFT substrate, 103 is a color filter, 104 is a black matrix, 105 is an electrode, 106 is an alignment film, and 107 is a liquid crystal layer. Reference numeral 108 indicates a TFT element (thin film transistor), and reference numeral 109 indicates a sealant. For easy understanding of the illustration, the vertical direction in the figure is extremely enlarged compared to the horizontal direction. The liquid crystal panel is basically a color filter substrate on the side (front side) where the image is viewed. 〇1 and a TFT substrate 102 on the reflective side (back side). The two light-transmitting substrates (usually composed of a glass substrate, but sometimes a transparent resin substrate) are used. A light-shielding film called a black matrix 104, a color filter 103, and the like are formed on the color filter substrate 101_.4 * 200521579 (2). On the TFT substrate 102, a driving element for driving liquid crystal is formed, for example, a TFT element; a liquid crystal driving electrode formed by a 08 or a transparent conductive film; and wirings connected to these. The black matrix 104 is formed of a chrome-evaporated film or a black resin. Here, only the black matrix for blindfolding is drawn so that light from the backlight does not leak out. In recent years, the above-mentioned liquid crystal panel has been manufactured using a manufacturing method called One Drop Fill (hereinafter abbreviated as O D F). The dripping method is disclosed in, for example, Japanese Patent Application Laid-Open No. 9-73 096. Hereinafter, the process of the dripping method will be described using FIG. 6. First, a TFT element 108 or a liquid crystal drive electrode is formed on one of the two glass substrates, and a black matrix 104 or a color filter 103 is formed on the other glass substrate 101. . On one of the glass substrates • 102, most of them have the width of UV-curable resin] ~;!. A 5 mm sealant 1 09 fence (hereinafter, referred to as a frame. The portion of the frame is a so-called liquid crystal screen) . Then, the liquid crystal was dropped into the above-mentioned fence in a vacuum and stored therein. The other glass substrate ιο1 was placed thereon, taken out under atmospheric pressure, and the sealant around the glass substrate 101 was irradiated with ultraviolet rays. As a result, the sealant 109 is cured, and the two glass substrates 101 and 102 are bonded (adhered). The sealant 109 serves as the seal of the liquid crystal layer 107 and the adhesion of the two glass substrates 101 and 102. In addition, although not shown, spherical fine particles called spacers are sprayed between the two glass substrates 101 and 102 to secure a space for sandwiching the liquid crystal layer 107. After the adhesion, the substrate is divided (cut) at each frame and assembled as a display screen of a computer or a television. 5-
V 200521579 (3) 第7圖是表示貼合兩片玻璃基板1 〇 1、1 02之液晶面 板的圖式。 如同圖所示般，在兩片玻璃基板101、102之間夾有 密封劑而所形成之液晶面板上，形成有多數（同圖中爲4 面）的畫廓。然後，塗布密封劑使可包圍各畫廓，並可覆 蓋該密封劑地形成黑矩陣104。 第8圖是表示放大第6圖所示之液晶面板之密封劑 109附近之構造的圖式。 φ 如同圖所示般，密封劑109是以500 // m〜1mm左右之 寬度成爲在黑矩陣104之下方。因此，即使自形成有黑矩 陣104之基板側執行光照射，密封劑1〇9也成爲黑矩陣 ‘ 1 04之陰影，殘留無法硬化之部分。但是，因製程上之情 · 況不同等，也有要求自形成有黑矩陣104之彩色濾光器基 板1 〇 1側予以光照射而執行貼合之情形。V 200521579 (3) Fig. 7 is a diagram showing a liquid crystal panel where two glass substrates 101 and 102 are bonded together. As shown in the figure, on the liquid crystal panel formed by sandwiching a sealant between two glass substrates 101 and 102, a large number (four faces in the same figure) are formed. Then, a sealant is applied so as to surround each contour, and a black matrix 104 is formed so as to cover the sealant. Fig. 8 is a diagram showing a structure in the vicinity of the sealant 109 of the liquid crystal panel shown in Fig. 6 in an enlarged manner. φ As shown in the figure, the sealant 109 is below the black matrix 104 with a width of about 500 // m to 1 mm. Therefore, even if light irradiation is performed from the substrate side on which the black matrix 104 is formed, the sealant 109 becomes a shadow of the black matrix ‘104, and a portion that cannot be hardened remains. However, depending on the manufacturing process and conditions, there may be a case where it is required to irradiate light from the side of the color filter substrate 101 where the black matrix 104 is formed to perform bonding.
自形成有黑矩陣之基板側執行光照射，執行液晶面板 之貼合的先行技術，所知的有以下2件。 H 日本專利第2828403號是揭示透過貼合基板之光，是 被配置在夾著液晶面板而與光照射部相向之位置上的光反 射構件所反射，藉由該反射光自黑矩陣之反對側而被照射 至密封劑而予以硬化。 再者，日本專利特開200 3 -2 07 7 90號公報是揭示使光 照射部傾斜，對液晶面板照射來自傾斜之光’硬化成爲黑 矩陣之陰影部分的密封劑’並且也利用來自被配置在與夾 著液晶面板而與光照射部相向之位置上之光反射構件的反 -6 - 200521579 (4) 射光，硬化密封劑。 〔專利文獻1〕日本專利第2 82 8403號 〔專利文獻2〕日本特開2003-207790號公報 【發明內容】 如上述公報所示般，若利用來自被配置在夾著液晶面 板而與光照射部相項之位置上的光反射構件之反射光，雖 然可以有效率硬化成爲黑矩陣之陰影部分的密封劑，但是 則有以下之問題。 第9圖是用以說明被記載於上述公報上之密封劑硬化 方法之問題點的圖式。 如同圖所示般，藉由光反射面所反射之光，被照射至 黑矩陣104下方之密封劑1〇9時，若光反射面和液晶面板 之間隔過窄，反射光則無法到達接近液晶107之後方的密 封劑109。另外，若間隔太寬，反射光通過寬度1〜1.5 mm 之密封劑過多，而使液晶部分也照射到光。液晶1 07因當 照射強紫外線時，引起特性變化，故以儘量減少紫外線之 照射爲佳。 因此，爲了使來自光反射面之反射光適當對密封劑予 以照射，必須在對光反射面具有適當間隔之範圍下，保持 液晶面板，必須在光反射面和液晶面板之間設置間隔設定 構件。該間隔設定構件必須注意以下所示之點。 (I )執行貼合之液晶面板是具有比1 m更大的此寸 ，且越來越朝向大型化。另外，因執行貼合之兩片玻璃基 ..7 - 200521579 (5) 板爲薄，故若僅支持四角或四邊，中央部則變成特別彎， 無法保持面板下面至光反射面爲止之間隔，故在四角或四 邊以外之部分，也須藉由間隔設定構件予以支持，需要保 持一定之手段。 (2 )貼合裝置是需要對應於畫廓大小不同之各種顯 示器面板之貼合處理。即是，被形成於所處理之面板上之 畫廓大小或形狀有各種變化。當畫廓之大小或形狀變化時 ’密封劑之位置也隨之變化。因此，間隔設定構件必須爲 即使密封劑之位置爲變化之時，亦可不妨礙射入至密封劑 之反射光者。 (3 )並且，液晶面板是必須保持固定，使不會在光 照射時因振動等而引起位置偏移，脫離光之照射區域， 本發明之目的是如上述般，提供使液晶面板不彎曲， 將液晶面板全區域相於對光反射面保持規定間隔，即使畫 廓之大小或形狀變化，密封劑之位置變化，間隔設定構件 也不會妨礙射入至密封劑之反射光，並且可以固定保持液 晶面板’於紫外線照射中，不會發生因振動而使液晶面板 自紫外線之照射區域脫離的顯示器面板的貼合裝置。 爲了解決上述課題，該發明是屬於將在兩片光透過性 基板之一方形成遮光部，並在上述兩片光透過性基板間夾 入紫外線硬化型密封劑和液晶而成爲一體形狀的顯示器面 板’載置在載物台上，對該顯示器面板，自形成有上述遮 光部之側照射紫外線，並使上述紫外線硬化型密封劑予以 硬化’而貼合上述兩片光透過性基板之顯示器面板的貼合 "8 200521579 (6) 裝置，其特徵爲： 載置上述顯示器面板之載物台是由具有供給真空之凹 部的基台；被設置在該基台上，具有多數貫通孔，表面爲 光反射面之光反射構件；和被插入於該光反射構件，具有 真空吸著孔之多數間隔物所構成，經由該間隔物將顯示器 面板載置在上述載物台上。 再者，載置上述顯示器面板之載物台，表面是由光反 射面所構成，在該光反射面上設置有多數光透過性之間隔 物，經由該間隔物將顯示器面板載置在上述載物台上。 並且，在上述載物台上形成有多數真空吸著孔，並在 上述光透過性之間隔物上形成有連通於該真空吸著孔的貫 通孔。 〔發明效果〕 若依據申請專利第1項所記載之發明，可以使顯示器 面板保持整個全區域不彎曲，再者，即使畫廓之大小或形 狀變化，並因準備間隔物位置不同之多數反射構件，而使 密封劑之位置變化之時，亦可變更成不妨礙由反射構被反 射而射入至密封劑之反射光的位置，並且可以固定保持顯 示器面板，於紫外線照射中，不會因振動而使顯示器移動 ’造成脫離紫外線之照射區域。 若依據申請專利第2項所記載之發明，則與申請專利 第1項相同，可以使顯示器面板整個全區域保持不彎曲， 再者’即使在畫廓之大小或形狀變化，且密封劑之位置變 -9 ~ 200521579 (7) 化之時，因間隔物爲光透過性，故依據該間隔物不會妨礙 自反射面反射而射入至密封劑之反射光。 若依據申請專利第3項所記載之發明，除了可達到與 申請專利第2項所記載之發明相同之效果外，因顯示器面 板被載物台吸著支撐，故於紫外線照射中，不會因振動而 使顯示器移動，造成脫離紫外線之照射區域。 【實施方式】 使用第1圖至第3圖說明本發明之第1實施形態。 第1圖是表示本實施形態所涉及之顯示器面板的貼合 裝置之構成的剖面圖。 於同圖中，1爲表示載物台，11爲表示構成載物台1 之基台，12爲表示被設置在基台11之供給真空的真空供 給凹部，13爲表示被設置在基台11上用以反射光的光反 射板，1 4爲表示被設置在對應於光反射板1 3之真空供給 凹部1 2之位置上的多數個貫通孔，1 5爲表示被設置在不 對應於光反射板1 3之真空供給凹部1 2的多數孔，1 6爲 表示被嵌合於貫通孔14，自光反射板13具有規定高度， 並具有當作間隔物發揮機能之真空吸著孔1 6 1的吸著銷， 17爲表示被嵌合於孔15，自光反射板13具有規定高度， 揮發當作間隔物之機能的銷，2位表示液晶面板（顯示器 面板），2 1爲表示構成液晶面板之彩色濾光器基板，2 2 爲表示構成液晶面板2之TFT基板，23爲表示被充塡在 基板2〗、22間之液晶，24爲表示封止液晶23，同時黏著 -10 ^ 200521579 (8) 基板21、22的紫外線硬化型密封劑，25爲表示被塗布在 彩色濾光器基板2 1之下面的液晶2 3和紫外線硬化型密封 劑24之境界區域的黑矩陣，3爲表示用以防止紫外線不 被照射至液晶面板2之部分，例如畫廓內之液晶或tft 基板電路兀件的遮光掩模，4爲表示紫外線照射部，4 1爲 表不放射紫外線之燈，4 2爲表示將來自燈4 1之光反射至 載物台1側之鏡。 並且，本實施例中，燈4 1是使用棒狀之高壓水銀燈 或鹵素燈。棒狀燈是爲了可以一起照射液晶面板之全面， 僅將對應於工作物之長度的棒狀燈，並列對應於工作之寬 度的條數。 如第1圖所示般·，執行貼合之液晶面板2是將形成有 .黑矩陣2 5之彩色濾光器基板2 1朝向紫外線照射部4側， 將TFT基板22朝向載物台1側而載置於載物台1上。被 載置於載物台1上之液晶面板2，是被放置在安裝於光反 射板1 3上之多數吸著銷1 6及銷1 7上。依據該些銷1 6、 1 7，光反射板1 3和液晶面板2是被保持規定間隔。來自 紫外線照射部4之紫外線一部分是被照射至自黑矩陣25 露出之紫外線硬化型密封劑24上，雖然硬化此，但是殘 留之大部分被光反射板1 3反射，被照射至塗布於黑矩陣 25之下方的紫外線硬化型密封劑24上。 第2圖是表示第1圖所示之載物台1之詳細構成的圖 式。 如同圖所示般，載物台1基本上是由基台11;被設 -11 -

H Japanese Patent No. 2828403 discloses that the light transmitted through the bonded substrate is reflected by a light reflecting member disposed at a position facing the light irradiating part with the liquid crystal panel interposed therebetween, and the reflected light is from the opposite side of the black matrix. It is irradiated with the sealant and hardened. Furthermore, Japanese Patent Laid-Open No. 200 3 -2 07 7 90 discloses that the light irradiating portion is tilted, and the liquid crystal panel is irradiated with light from the tilt to 'curing a sealant which is hardened to become a shadow portion of the black matrix'. Anti-6-200521579 of a light reflecting member facing a light irradiating part with a liquid crystal panel sandwiched therebetween (4) Light is irradiated and the sealant is hardened. [Patent Document 1] Japanese Patent No. 2 82 8403 [Patent Document 2] Japanese Patent Application Laid-Open No. 2003-207790 [Summary of the Invention] As described in the above-mentioned publication, when a light source is irradiated with light from a liquid crystal panel placed between Although the reflected light of the light reflecting member at the position of the phase term can be hardened effectively as a sealant for the shadow portion of the black matrix, it has the following problems. Fig. 9 is a diagram for explaining the problems of the sealant hardening method described in the aforementioned publication. As shown in the figure, when the light reflected by the light reflecting surface is irradiated to the sealing agent 10 below the black matrix 104, if the distance between the light reflecting surface and the liquid crystal panel is too narrow, the reflected light cannot reach the liquid crystal 107. Following the sealant 109. In addition, if the interval is too wide, the reflected light passes through a sealant having a width of 1 to 1.5 mm, and the liquid crystal portion is also irradiated with light. Since the LCD 1 07 changes its characteristics when it is irradiated with strong ultraviolet rays, it is better to minimize the exposure to ultraviolet rays. Therefore, in order to properly irradiate the sealant with the reflected light from the light reflecting surface, it is necessary to hold the liquid crystal panel within a range having a proper distance from the light reflecting surface, and a gap setting member must be provided between the light reflecting surface and the liquid crystal panel. This interval setting member must pay attention to the following points. (I) The liquid crystal panel to be bonded has a size larger than 1 m, and it is becoming larger and larger. In addition, since the two glass substrates for lamination .. 7-200521579 (5) are thin, if only four corners or four sides are supported, the central part becomes particularly curved, and the interval between the bottom of the panel and the light reflecting surface cannot be maintained. Therefore, the part other than the four corners or four sides must also be supported by the interval setting member, and certain means must be maintained. (2) The laminating device requires laminating processing corresponding to various display panels with different drawing sizes. That is, there are various variations in the size or shape of the contours formed on the panel being processed. When the size or shape of the outline changes, the position of the sealant also changes. Therefore, the interval setting member must be a member that does not interfere with the reflected light incident on the sealant even when the position of the sealant is changed. (3) Moreover, the liquid crystal panel must be kept fixed so as not to be displaced due to vibration or the like when irradiated with light, and separated from the area irradiated by light. The object of the present invention is to provide the liquid crystal panel without bending as described above. The entire area of the liquid crystal panel is kept at a predetermined interval from the light-reflecting surface. Even if the size or shape of the outline changes, and the position of the sealant changes, the interval setting member does not hinder the reflected light incident on the sealant, and can be fixedly held. The liquid crystal panel is a bonding device for a display panel that does not detach the liquid crystal panel from the ultraviolet irradiation area due to vibration during ultraviolet irradiation. In order to solve the above problems, the invention is a display panel in which a light-shielding portion is formed on one of two light-transmitting substrates, and an ultraviolet curable sealant and a liquid crystal are sandwiched between the two light-transmitting substrates. The display panel is placed on a stage, and the display panel is irradiated with ultraviolet rays from the side where the light-shielding portion is formed, and the ultraviolet-curable sealant is cured. (8) 200521579 (6) device, characterized in that: the stage on which the display panel is placed is a base having a recess for supplying vacuum; the base is provided on the base with a large number of through holes and the surface is light A light reflecting member on the reflecting surface; and a plurality of spacers inserted into the light reflecting member and having vacuum suction holes, and the display panel is placed on the stage via the spacers. The surface of the stage on which the display panel is placed is composed of a light reflecting surface, and a plurality of light-transmitting spacers are provided on the light reflecting surface. The display panel is placed on the stage through the spacer. On the stage. A plurality of vacuum suction holes are formed in the stage, and a through hole is formed in the light-transmitting spacer to communicate with the vacuum suction holes. [Effects of the Invention] According to the invention described in the first patent application, the entire area of the display panel can be kept from bending. Furthermore, even if the size or shape of the outline changes, and a large number of reflecting members with different spacer positions are prepared. When changing the position of the sealant, it can also be changed to a position that does not prevent the reflected light from being reflected by the reflective structure and incident on the sealant. It can also hold the display panel in a fixed position. And moving the display 'causes it to escape from the ultraviolet irradiation area. According to the invention described in the second patent application, the same as the first patent application, the entire area of the display panel can be kept unbent. Furthermore, even if the size or shape of the outline changes, and the position of the sealant (-9) 200521579 (7) When the spacer is light-transmissive, the spacer will not hinder reflection from the reflective surface and will reflect the reflected light into the sealant. According to the invention described in the patent application No. 3, in addition to achieving the same effect as the invention described in the patent application No. 2, since the display panel is supported by the stage, it is not affected by ultraviolet radiation. Vibration causes the display to move, leaving the area irradiated by ultraviolet rays. [Embodiment] A first embodiment of the present invention will be described with reference to Figs. 1 to 3.

The color filter substrate of the liquid crystal panel, 2 2 is a TFT substrate constituting the liquid crystal panel 2, 23 is a liquid crystal filled between the substrate 2 and 22, and 24 is a liquid crystal 23 sealed, and at the same time -10 ^ 200521579 (8) UV-curable sealants for substrates 21 and 22, 25 for the table The black matrix of the boundary region of the liquid crystal 2 3 and the ultraviolet curable sealant 24 coated on the lower side of the color filter substrate 2 1, 3 is a part to prevent ultraviolet rays from being irradiated to the liquid crystal panel 2, such as a picture frame The light-shielding mask of the liquid crystal or tft substrate circuit element inside, 4 is the ultraviolet irradiation part, 41 is the lamp that does not emit ultraviolet rays, and 42 is the light reflecting the light from the lamp 41 to the side of the stage 1. mirror. Further, in the present embodiment, the lamp 41 is a high-pressure mercury lamp or a halogen lamp using a rod shape. In order to illuminate the entire surface of the liquid crystal panel together, the rod-shaped lamps are only aligned with the number of rod-shaped lamps corresponding to the length of the work. As shown in FIG. 1, the bonded liquid crystal panel 2 is formed with a black matrix 25 and a color filter substrate 2 1 facing the ultraviolet irradiation part 4 side, and the TFT substrate 22 facing the stage 1 side. Instead, it is placed on the stage 1. The liquid crystal panel 2 placed on the stage 1 is placed on the majority of the absorbing pins 16 and 17 mounted on the light reflecting plate 13. According to these pins 16 and 17, the light reflecting plate 13 and the liquid crystal panel 2 are maintained at a predetermined interval. Part of the ultraviolet rays from the ultraviolet irradiation section 4 is irradiated onto the ultraviolet-curable sealant 24 exposed from the black matrix 25. Although hardened, most of the remaining light is reflected by the light reflecting plate 13 and irradiated to the black matrix 25 below the UV-curable sealant 24. Fig. 2 is a view showing a detailed configuration of the stage 1 shown in Fig. 1. As shown in the figure, the stage 1 is basically composed of the base 11; it is set to -11-200521579 (9) the light reflecting plate placed on the base 11 and the suction pin 16 mounted on the light reflecting plate 13 And pins 1 to 7. The base 11 is a portion that becomes the base of the stage 1. On the four corners of the base 11, groove-shaped vacuum supply recesses 12 are formed in an elongated shape toward the center of the base 11. A vacuum line (not shown) of the liquid crystal panel 2 for holding and performing bonding is connected to the vacuum supply recess 12 to perform vacuum supply. The light reflecting plate 13 is a thin plate-like member having a thickness of about 2 mm and is provided on a base. The surface of 11 allows the vacuum supply recess 12 which can cover the base 11 to be fixed to the base with fixing screws or the like. In order to reflect the ultraviolet rays on the light reflecting plate 1 to 3, it is possible to use aluminum whose brightness is achieved by electrolytic honing or chemical honing, or a material which has been subjected to white anti-corrosion aluminum treatment. When a reflection plate treated with white anti-corrosion aluminum is used, the reflected light often becomes a scattered light component. A hole is formed in the light reflecting plate 13 for mounting a plurality of suction pins 16 and 17 to keep the distance between the light reflecting plate 13 and the liquid crystal panel 2 constant. Among them, the hole corresponding to the position of the vacuum supply recessed portion 12 of the base 11 is a through-hole 14, and here, a suction pin 16 having a vacuum suction hole 16 is inserted. Vacuum is not supplied to the pins 17 provided at positions which do not correspond to the vacuum supply recesses 12 provided on the base 11. Therefore, the hole 15 for inserting the pin 17 may be determined by the position of the pin 17 and may not be a through hole. Of course, it is also possible to use a suction pin 16 instead of the pin 17 in the phase 17 even if there is no vacuum suction hole. The position where the absorbing pin 16 is mounted on the light reflecting plate 13 is set in accordance with the position of the sealant 24 of the liquid crystal panel 2 to be bonded. That is, • 12, 200521579 (10) It is installed at a position that does not prevent the reflected light from entering the sealant 24 which does not impinge on the inner side of the frame that does not irradiate ultraviolet rays (the liquid crystal part). The suction pin 16 has a head portion having a flat surface on which the liquid crystal panel 2 is placed and having a predetermined height, and a head portion through which the light reflection plate 13 is inserted into the through hole 14. Furthermore, a vacuum suction hole 1 6 1 is provided which penetrates from the head to the head. The materials of the suction pins 16 and 17 are preferably resins called engineering plastics with excellent heat resistance, strength, and bending elasticity. Specifically, polyetheretherketone materials (called PEEK materials) are used. The heights of the heads of the absorbing pins 16 and 17 are the distance from the lower surface of the liquid crystal panel 2 to the light reflecting plate 13 and the dimensions suitable in advance are obtained through experiments. That is, the distance between the liquid crystal panel 2 and the light reflecting plate 13 is changed, and a hardening test of the sealant 24 is performed, so that the sealant 24 coated on the shadow of the black matrix 25 can be optimally hardened. According to the results of experiments with several contour patterns, it can be seen that the distance between the lower surface of the liquid crystal panel 2 and the light reflecting plate 13 is most preferably in the range of 2 mm to 8 mm (preferably about 4 mm) ° and the 'suction pin 16 is As shown in FIG. 3, the head of the suction pin 6 is inserted into the through hole 14 of the light reflecting plate 13 and fixed from the back side. The same applies to pins 1 7. In FIGS. 1 and 2, in order to perform the bonding of the liquid crystal panel, first, “the light reflecting plate 13 on which the absorbing pins 16 and the pins 17 are mounted is placed on the light reflecting plate 13” to be fixed. Fasten with screws. Next, when a vacuum is supplied to the vacuum supply recessed portion 12 of the base 11, the vacuum supply recessed portion 12 is decompressed 'and the vacuum is supplied to the vacuum suction hole 16 of the suction pin 16. When the liquid crystal panel 2 to be bonded is placed on the suction 13- 200521579 (11) with the pins 16 and 17 attached, the liquid crystal panel 2 is based on the vacuum supplied to the through holes 14 of the suction pins 16. It is fixed and held on the Greek pin 16. The pins 1 7 other than the suction pins 16 can prevent the liquid crystal panel 2 from bending by its own weight, and maintain a certain distance from the lower surface of the liquid crystal panel 2 and the light reflecting plate 1 3. Thereafter, ultraviolet rays are irradiated by the ultraviolet irradiation section 4. According to the invention of this embodiment, the light reflecting plate 13 with the absorbing pins 16 and 17 is installed in accordance with the size of the liquid crystal panel 2 to be bonded or the position of the sealant 24. It is necessary to change the arrangement of the absorbing pins in advance. 16 and pin 17 positions. According to this, it can be exchanged according to the size of the liquid crystal panel to be processed or the position of the sealant 24. As a result, it can correspond to the bonding of various liquid crystal panels (display panels). The second and third embodiments of the present invention will be described with reference to Figs. 4 and 5. Fig. 4 is a cross-sectional view showing the configuration of a bonding device for a display panel according to this embodiment. In the same figure, 1 indicates the stage '11 and the base constituting the stage 1 '. 1 8 indicates the vacuum circuit 7 for holding and holding the liquid crystal (display panel) panel 2 when it is connected to light irradiation. The vacuum suction hole for supplying vacuum, 11a is a light reflecting surface that reflects light formed on the base 11. '10 is a surface that is not connected to the light reflecting surface 11a. The self-light reflecting surface iia has a majority of a predetermined height. A light-transmitting spacer '19 made of a synthetic quartz glass or the like indicates that it communicates with the vacuum suction hole 18 of the stage 1 and is formed on the liquid crystal panel 2 placed on the upper part for vacuum suction. Interval ~ 14 ^ 200521579 (12) Through-holes in object 10 are 2 for liquid crystal panel, 21 for color filter substrate for crystal panel 2, 22 for TFT substrate constituting liquid crystal, and 23 for substrate. 2_4 filled between the substrates 21 and 22 represents a sealing liquid crystal 2 3 ′, and is a purifying sealant which adheres the substrates 2 1 and 2 2 ′ 2 5 represents a liquid crystal substrate formed on the surface of the color filter: 2 And UV-curable sealant 2 4 of the boundary area moment J car, 3 is used to indicate Ultraviolet rays are not irradiated to the liquid crystal surface portion. For example, the mold of liquid crystal or TF T substrate circuit elements in the outline, 4 is an ultraviolet irradiated part, and 41 is a cross-sectional view showing radiation in a direction orthogonal to the length. Ultraviolet lamp, 4 2 is a mirror reflecting the light from the lamp 41 to the side of the stage 丨, 6 is a switch to supply vacuum to the empty suction hole 1 of the stage 1 due to the size or shape of the panel 2 The solenoid valve, 7 is a vacuum circuit. The light reflecting surface 1 1 a of the stage 1 may be a base 11 made of aluminum or the like, and the surface may be honed. Furthermore, a metal plate or the like that reflects light may be placed on the foundation. Furthermore, the vacuum suction holes 18 provided in the carrier are preferably limited to a minimum number in order to minimize the influence of reflected light. In addition, the spacers 10 installed on the stage 1 are installed according to the adhesive (for example, a silicon-based adhesive), and the number or interval of the spacers 10 is set according to the liquid crystal panel to be processed. Weight. Moreover, the lamp 4 1 is a rod-shaped high-pressure mercury lamp or a halogen-shaped lamp, so that it can illuminate the entire surface of the liquid crystal panel together. The direction indicates that the size of the true metal made of liquid crystal should be 1 1 1 on the stage 1 and the size or light between the light transmission equipment. Sticks 15-200521579 (13) The length of the rod-shaped lamp of the crop, and the number of bars corresponding to the width of the work. In addition, in the above description, although the use of the light-shielding mask 3 is described, there may be a case where the light is not irradiated with the light-shielding mask. At this time, the color filter formed on the color filter substrate 21 is used instead of the light-shielding mask. Fig. 5 is a detailed configuration diagram showing the stage 1 and the spacers 10 configured in Fig. 4. As shown in the figure, a plurality of spacers 10 are provided on the light reflecting surface 1 1 a of the surface of the base 1 1 of the stage 1, and the spacer 10 is formed with a vacuum suction on the stage 1. The holes 10 communicate with the through holes 19. The spacers 10 are mounted on the light reflecting surface 11a of the base 11 with a light-transmitting adhesive as described above. First, a plurality of spacers 10 are prepared, and they are mounted on the surface of the stage 1 in accordance with the positions of the vacuum suction holes 18 and the through holes 19 of the stage 1. For mounting, use an ultraviolet-transmitting adhesive. The number or interval of the mounting spacers 10 is set in accordance with the size or weight of the liquid crystal panel 2 so as not to cause bending. In addition, the height of the spacer 10, that is, the distance from the lower surface of the liquid crystal panel 2 to the light reflecting surface 11a of the stage 1, is determined by experiments to fit this inch in advance. That is, the hardening test of the sealant 24 is performed by changing the interval between the liquid crystal panel 2 and the light reflecting surface 1 1 a, so that the sealant 24 coated on the shadow of the black matrix 25 can be optimally hardened. According to the results of experiments with several contour patterns, it can be seen that the interval between the lower surface of the liquid crystal panel 2 and the light reflecting surface] la is most suitable for a range of 2 mm to 8 mm (preferably about 4 mm). -16- 200521579 (14) The light-reflecting surface 11a of the stage 1 will irradiate the light reflected by the light-reflecting surface 11a with the ultraviolet curing sealant 24 under the black matrix 25 to make the sealant 2 4 to be hardened ', so it is better to have no non-reflected light portion or step, etc., which affects the amount of light or the path of the reflected light. Therefore, it is necessary to limit the vacuum suction holes 18 provided on the surface of the stage 1 to the minimum required. In addition, from the reason described above, it is known that the fixed spacer 10 and the surface of the stage 1 are not fixed by the step difference or vacuum suction, but are fixed by an adhesive having ultraviolet permeability. In addition, known adhesives are commercially available, such as hard-locked OP / UV manufactured by Denka Kogyo Co., Ltd. and the like. Such adhesives are used for the bonding of optical lenses of glass or glasses or glass display stands. The vacuum suction holes 18 are divided into a plurality of groups in accordance with the size of the liquid crystal panel 2 to be sucked, and vacuum is supplied from the vacuum lines 7 divided into groups. In FIG. 5, as shown by the dotted line, if it is a small liquid crystal panel 2, as shown in FIG. 4, the solenoid valve A is turned on, and only vacuum is supplied to the vacuum suction hole near the center of the stage 丨1 8. Further, as shown in a dotted line, if the large liquid crystal panel 2 'is shown in FIG. 4, both of the solenoid valve a and the solenoid valve B are turned on' to supply a vacuum to the entire vacuum suction hole 18. Next, a bonding device for a known display panel according to this embodiment will be described. As shown in FIG. 4, the liquid crystal panel 2 to be bonded is such that the color filter substrate 2 1 on which the black matrix 25 is formed is directed toward the ultraviolet irradiation portion 4 side, and -17 200521579 (15) faces the TFT substrate 22. The stage 1 is placed on the stage 1 side. The liquid crystal panel 2 placed on the stage 1 is placed on a plurality of light-transmitting spacers 2 mounted on the light reflecting surface 1 1 a. According to the majority of the spacers 10 ', the liquid crystal panel 2 is held without being bent, and a predetermined distance is maintained from the lower surface of the liquid crystal panel 2 to the light reflecting surface 1 1a. When a vacuum is supplied from the vacuum line 7 to the stage 1, the vacuum is supplied to the through holes 19 of the spacer 1 through the vacuum suction holes 18 of the stage 1 according to the space supplied to the spacer 1 0. In the vacuum of the through hole 19, the liquid crystal panel 2 is held and fixed on the spacer. Since the spacer 10 is fixed to the stage 1 by an adhesive, the liquid crystal panel 2 is fixed to the stage 1 through the spacer 10. The ultraviolet light which hardens the sealant 24 from the ultraviolet irradiation section 4 is irradiated toward the liquid crystal panel 2. The light irradiated by the ultraviolet irradiation section 4 is diffused light, and the irradiated light also contains components which are obliquely incident on the light reflecting surface 1 1 a of the stage 1 to the liquid crystal panel 2 to be bonded. In addition, the light-shielding mask 3 described above may not be used. Part of the ultraviolet rays incident obliquely from the ultraviolet irradiation section 4 to the liquid crystal panel 2 is irradiated to the ultraviolet curing sealant 24 protruding from the black matrix 25. Although hardened, most of the remaining is formed on the liquid crystal panel. Between the picture 2 and the picture, the light reflecting plate 1 is incident on the light reflecting plate 1 with or without the light-transmitting spacer 10, and a is reflected in accordance with the incident angle, and is irradiated to the coated black UV curing sealant 24 under matrix 2 5 and UV curing sealant 24 under curing. -18- 200521579 (16) As mentioned above, the spacer 10 is light-transmissive, so even if the positions of the spacer 10 and the UV-curable sealant 24 overlap, it will not cause an overcast-shadow according to the stage 1. The light-reflecting surface 1 1 a and the reflected light are irradiated onto the ultraviolet-curable sealant 2 4.
