[0002] 在光學顯示裝置的製造現場,一直採用滾輸至面板(Roll・To・Panel(RTP))方式的製造方法(例如,專利文獻1)。在RTP方式中,通常,用以下的方式製造光學顯示裝置。首先,將具有預定寬度的光學薄膜層積體從滾輪送出。光學薄膜層積體包含:載體薄膜、形成於載體薄膜的一方之面的黏著劑層、藉由黏著劑層來支持於載體薄膜上的光學薄膜。光學薄膜可以是單層也可以是複數層。在被送出的光學薄膜層積體中,通常,藉由在寬度方向上連續地劃入切入線,在鄰接的切入線之間形成片狀的光學薄膜。   [0003] 在載體薄膜上連續地被支持的形成片狀的光學薄膜,藉由配置於貼合位置附近的剝離機構來從載體薄膜上與黏著劑層一同剝離,並送至貼合位置。在剝離機構中,光學薄膜層積體的載體薄膜側,被卷入具有對向於貼合位置的頂部的略楔型的剝離機構的頂部。光學薄膜,藉由將被剝離機構卷入的載體薄膜,在與向貼合位置的光學薄膜的搬送方向概略呈相反的方向折返並進行搬送,從載體薄膜上與黏著劑層一同被剝離。到達貼合位置的光學薄膜,藉由具有一對貼合滾輪的貼合機構,來與被搬送至別的貼合位置的面板的所對應的貼合面作貼合。   [0004] 另一方面,近年來在光學顯示裝置中,小型化、薄型化、及輕量化更為進展,隨之要求將包圍液晶顯示區域的框部分的狹小化,亦即不只是窄邊框化還要求要無邊框化。作為因應這種要求的方法,例如,如專利文獻2所記載的,提案有將比液晶面板還大的光學薄膜貼合至液晶面板的一面,將從貼合至液晶面板的一面的光學薄膜的端部露出的光學薄膜的剩餘部分沿著液晶面板的端部切離,接著,在一面貼合有光學薄膜的液晶面板的另一面貼合比液晶面板還大的光學薄膜,將從貼合至液晶面板的另一面的光學薄膜的端部露出的光學薄膜的剩餘部分沿著液晶面板的端部切離,藉此,來製造光學的顯示裝置的層積體的技術。   [0005] 在專利文獻2中,在一連的製造裝置內進行切離剩餘部分的工程。具體來說,在製造裝置內在液晶面板的兩面依序被貼合的光學薄膜的剩餘部分,根據情況在每次,以從液晶面板的兩面的全部4邊露出的狀態層積,因此,從作為製造裝置的成品得到的光學顯示裝置,從液晶面板的兩面將4邊的所有剩餘部分沿著液晶面板的兩面的端部切離,光學薄膜成為對應貼合面的大小的層積體。   [0006] 再來,例如,如專利文獻3或專利文獻4所記載的,提案有在液晶面板的一面將光學薄膜露出而貼合,在液晶面板的另一面以不露出而貼合的生產系統。在其等中,將從液晶面板的一面露出而貼合的剩餘部分切離的工程,與專利文獻2的情形一樣,在一連串的生產系統內進行。   [0007] 具體來說,貼合至液晶面板的一面的光學薄膜的剩餘部分,以從液晶面板的全部4邊露出的狀態被層積,作為從生產系統的成品得到的光學顯示裝置,因為將貼合至液晶面板的一面的光學薄膜的剩餘部分沿著液晶面板的端部切離,將貼合至液晶面板的另一面的光學薄膜以不露出的方式貼合,液晶面板的兩面的光學薄膜成為對應貼合面的大小,為與專利文獻2的情形相同的層積體。   [0008] 液晶顯示裝置,在液晶面板的兩面將偏光薄膜以吸收軸成為正交偏光關係的方式而沿著基準線(對準標記)貼合是為了實現液晶顯示裝置的光開關機能。如圖8的參考圖所示,偏光薄膜具有包含顯示區域而在液晶面板內部的黑矩陣上或超過黑矩陣的區域的大小。   [0009] 液晶顯示裝置的構造如圖1的概略圖可以明白,由至少在液晶的兩面包含使彩色濾光片隔介的玻璃基板的液晶面板的CF側的構件、及包含配光膜及使透明電極隔介的玻璃基板的液晶面板的TFT側的構件所形成。通常,液晶面板的TFT側的長邊之中的1邊,作為內藏透明電極的端子,成為比液晶面板的CF側的對應的1邊還突出的構造。在CF側的玻璃基板及TFT側的各個玻璃基板,以偏光薄膜隔著光學補償薄膜,且吸收軸成為正交偏光關係的方式貼合。因此,貼合液晶面板的偏光薄膜的區域外,通常,成為透過的區域。 [先前技術文獻] [專利文獻]   [0010]   [專利文獻1] 特許第4377964號公報   [專利文獻2] 特開2014-228563號公報   [專利文獻3] 特開2013-137538號公報   [專利文獻4] 特開2014-224911號公報[0002] In the manufacturing site of optical display devices, a roll-to-panel (Roll-To-Panel (RTP)) manufacturing method has been adopted (for example, Patent Document 1). In the RTP method, generally, an optical display device is manufactured in the following manner. First, the optical film laminate having a predetermined width is sent out from the roller. The optical film laminate includes a carrier film, an adhesive layer formed on one side of the carrier film, and an optical film supported on the carrier film by the adhesive layer. The optical film may be a single layer or multiple layers. In the optical film laminate that is sent out, normally, a sheet-shaped optical film is formed between adjacent cut lines by continuously scribing cut lines in the width direction.  [0003] The sheet-like optical film continuously supported on the carrier film is peeled from the carrier film together with the adhesive layer by a peeling mechanism arranged near the bonding position and sent to the bonding position. In the peeling mechanism, the carrier film side of the optical film laminate is wound around the top of the slightly wedge-shaped peeling mechanism having the top facing the bonding position. The optical film is transported by turning the carrier film rolled in by the peeling mechanism in a direction substantially opposite to the transporting direction of the optical film to the bonding position, and is peeled from the carrier film together with the adhesive layer. The optical film that has reached the bonding position is bonded to the corresponding bonding surface of the panel that is transported to another bonding position by a bonding mechanism having a pair of bonding rollers. [0004] On the other hand, in recent years, in optical display devices, miniaturization, thinning, and weight reduction have progressed, and there has been a demand for narrowing the frame portion surrounding the liquid crystal display area, that is, not only narrowing the frame It is also required to be borderless. As a method to meet this requirement, for example, as described in Patent Document 2, it is proposed to bond an optical film larger than a liquid crystal panel to one side of the liquid crystal panel, and to bond an optical film to one side of the liquid crystal panel. The remaining part of the optical film exposed at the end is cut away along the end of the liquid crystal panel. Then, an optical film larger than the liquid crystal panel is laminated on the other side of the liquid crystal panel with the optical film laminated on one side. The remaining part of the optical film exposed at the end of the optical film on the other side of the liquid crystal panel is cut along the end of the liquid crystal panel to produce a laminate of an optical display device.  [0005] In Patent Document 2, the process of cutting off the remaining part is performed in a series of manufacturing equipment. Specifically, the remaining part of the optical film that is sequentially laminated on both sides of the liquid crystal panel in the manufacturing device is laminated in a state exposed from all four sides of both sides of the liquid crystal panel depending on the situation. In the optical display device obtained as the final product of the manufacturing device, all the remaining parts of the four sides are cut from both sides of the liquid crystal panel along the ends of the two sides of the liquid crystal panel, and the optical film becomes a laminated body corresponding to the size of the bonding surface. [0006] Furthermore, for example, as described in Patent Document 3 or Patent Document 4, a production system is proposed in which an optical film is exposed on one side of a liquid crystal panel to be bonded, and the other side of the liquid crystal panel is bonded without being exposed. . Among them, the process of cutting off the remaining part of the bonding from one side of the liquid crystal panel is performed in a series of production systems, as in the case of Patent Document 2. [0007] Specifically, the remaining part of the optical film bonded to one side of the liquid crystal panel is laminated in a state exposed from all four sides of the liquid crystal panel, as an optical display device obtained from the finished product of the production system, because The remaining part of the optical film bonded to one side of the liquid crystal panel is cut away along the end of the liquid crystal panel, and the optical film bonded to the other side of the liquid crystal panel is bonded so as not to be exposed. The optical film on both sides of the liquid crystal panel It corresponds to the size of the bonding surface, and is the same laminate as in the case of Patent Document 2.  [0008] In the liquid crystal display device, polarizing films are bonded along the reference line (alignment mark) so that the absorption axis becomes orthogonal polarization relationship on both sides of the liquid crystal panel in order to realize the optical switch function of the liquid crystal display device. As shown in the reference diagram of FIG. 8, the polarizing film has a size including a display area on the black matrix inside the liquid crystal panel or an area exceeding the black matrix. [0009] The structure of the liquid crystal display device is as clear as the schematic diagram of FIG. 1. The CF side member of the liquid crystal panel including the glass substrate interposed by the color filter on at least both sides of the liquid crystal, and the light distribution film and the use It is formed by a member on the TFT side of a liquid crystal panel of a glass substrate interposed by a transparent electrode. Generally, one side of the long sides on the TFT side of the liquid crystal panel, as a terminal with a built-in transparent electrode, has a structure that protrudes more than the corresponding one side on the CF side of the liquid crystal panel. The glass substrate on the CF side and the glass substrate on the TFT side were bonded so that the polarizing film had the optical compensation film interposed therebetween, and the absorption axis was in a relationship of orthogonal polarization. Therefore, outside the area where the polarizing film of the liquid crystal panel is bonded, it is usually a transmission area.

[發明所欲解決的問題]   [0011] 光學顯示裝置的無邊框化,是藉由在RTP方式的製造裝置及製造方法中,從液晶面板的端部將光學薄膜以露出的狀態來貼合液晶面板與光學薄膜之後,將光學薄膜的露出部分即剩餘部分沿著液晶面板的端部切離而達成。   [0012] 不過,如專利文獻2至4所提案的,在一連的製造線中,在從液晶面板的端部露出而貼合後將周緣的剩餘部分切離時,因為將所有剩餘部分精密地切離需要時間,生產性顯著地下降。   [0013] 又,例如,根據如面板製造商這種具有液晶面板的製造工程的顧客,會要求如何將周緣的剩餘部分切離(例如,是否沿著液晶面板的端部切離、是否設置數釐米的露出帶而切離等)的自由度,周緣的剩餘部分的切離加工,是顧客依自己的需求來進行的。   [0014] 在這裡,要求不將大量的相對於液晶面板而使光學薄膜露出並貼合的液晶面板周緣的剩餘部分切離,將光學薄膜的剩餘部分留下而提供光學顯示裝置的層積體。   [0015] 但是,在RTP方式中,欲在一連的製造線中不將液晶面板的周緣的剩餘部分切離而將光學薄膜的剩餘部分留下而提供層積體的話,將液晶面板及光學薄膜,以從液晶面板的兩面的4邊露出的狀態將液晶面板與光學薄膜貼合後,在成為具有偏光薄膜的光學薄膜時,為了使偏光薄膜的吸收軸成為正交偏光關係,確認成為液晶面板的顯示區域的基準點的對準標記變得困難。因此,液晶面板與偏光薄膜的對位變得困難。   [0016] 又,將光學薄膜的剩餘部分留下的層積體,因為光學薄膜的周緣為可撓性而變得不穩定,無法利用從搬送方向的側面抵接的位置調整機構,需要另外準備複雜的位置調整機構。   [0017] 專利文獻2至專利文獻4所記載的RTP方式的所有製造裝置及製造方法,在製造工程中或生產系統中,將從液晶面板露出而貼合並將光學薄膜的剩餘部分的全部切離,作為由此方式製造的製品所得到的光學顯示裝置,當然是由無光學薄膜的露出部分的層積體所形成者。   [0018] 又,專利文獻3及專利文獻4所揭示的實施形態,都僅揭示在TFT側從4邊露出而貼合偏光薄膜後在CF側以無露出的方式貼合偏光薄膜的構成,並未揭示先以不在TFT側露出的方式貼合偏光薄膜,接著在CF側露出而貼合偏光薄膜的構成。   [0019] 再來的技術課題為在製造裝置內或生產系統內也一樣,即便因應顧客的新要求而提供將僅在TFT側從4邊露出使偏光薄膜貼合而在CF側以不露出的方式貼合偏光薄膜的液晶顯示裝置的層積體,在切離突出部分的剩餘部分時,無法將損傷內藏TFT側的端子的部位之危險去除。又,剩餘部分為4邊所有的層積體時,無法排除抵接於檢查部正前方的液晶面板位置調整機構而變形,而從此處發生裂縫等的危險。本發明為挑戰該技術課題而實現者。 [解決問題的手段]   [0020] 上述課題,能夠藉由:在長方形的液晶面板的兩面將具有偏光薄膜的光學薄膜,以吸收軸成為正交偏光關係的方式層積的光學的顯示裝置的層積體,其中,液晶面板的一面即TFT側的面的光學薄膜具有對應液晶面板的寬度或長度的寬度或長度,液晶面板的另一面即CF側的面的光學薄膜具有比液晶面板的寬度或長度之中任一者還大的寬度或長度的層積體來解決。根據這種層積體,因為能夠使從液晶面板露出而層積的光學薄膜的剩餘部切離的工程,在與一連的製造裝置不同的別的裝置實施,能使生產性大幅地提升。   又,因為本發明的層積體,係在TFT側的面的光學薄膜、與CF側的面的光學薄膜重疊的處所成為正交偏光關係,在TFT側的面的光學薄膜的外周透過CF側的面的光學薄膜而能夠容易讀取液晶面板的對準標記及液晶面板的邊緣。再來,本發明的層積體,因為在組裝顯示裝置時成為目視側的CF側的面,層積具有比液晶面板的寬度或長度之中的至少一者還大的寬度或長度的光學薄膜,之後,藉由將從液晶面板露出而貼合的光學薄膜的剩餘部切離,能使目視側無邊框化。   [0021] 本發明在其一態樣中,提供光學顯示裝置的層積體。這是如圖1的概略圖所示那樣,具體來說,係在長方形的液晶面板5的兩面,以吸收軸成為正交偏光關係的方式,將具有第1偏光薄膜的光學薄膜10及具有第2偏光薄膜的光學薄膜20作層積的層積體6。又,這是在液晶面板5的一面即TFT側52的面貼合具有對應液晶面板5的寬度或長度的寬度或長度的第1光學薄膜10,在液晶面板5的另一面即CF側51的面貼合具有比液晶面板5的寬度或長度之中至少一者還大的寬度或長度的第2光學薄膜之層積體6。層積體6,又以貼合在CF側51的面的第2光學薄膜20不從TFT側52的長邊之中的1邊側52y突出的方式被層積。若是該種層積體的話,因為能使位置調整機構530抵接至1邊側52y,能使層積體6的位置調整變得容易。   [0022] 由圖1可明白,為液晶面板5由CF側51的構件與TFT側52的構件所構成,層積體6更在第2光學薄膜20在未突出的液晶面板5的TFT側52的構件的長邊52y,在液晶面板5形成TFT側52的構件從CF側51的構件突出的突出部520,在突出部520的CF側的面521形成端子50,貼合於CF側51的面的第2光學薄膜20以未覆蓋突出部520的端子50的方式被貼合的層積體6。若是這種層積體6的話,以未覆蓋端子50的方式來貼合第2光學薄膜20,與覆蓋端子50的方式貼合第2光學薄膜20的層積體相比,就不需要追加將覆蓋端子50的第2光學薄膜20的剩餘部分切斷除去的步驟,不會傷害到端子50。   [0023] 本發明在其他態樣中,提供光學顯示裝置的層積體的製造方法。本發明作為一實施態樣,詳細如同後述,具有圖4的模式圖及圖5的流程圖所示的RTP方式的方法、及圖6的模式圖及圖7的流程圖所示的枚葉型方式的方法。將全體模式地表示的RTP方式的方法如圖2及圖3所示。   [0024] 本發明不管是RTP方式的方法還是枚葉型方式的方法,都是基於以下所示的構成的方法。   具體來說,如圖2及圖3的模式圖所示,為利用由具有對應長方形的液晶面板5的寬度或長度的寬度或長度,且具有在第1離型薄膜上藉由黏著劑層所支持的第1偏光薄膜的光學薄膜10所形成的第1光學薄膜層積體1、以及由具有比液晶面板5的寬度或長度之中至少一者還大的寬度或長度,且具有在第2離型薄膜即第2離形薄膜上藉由黏著劑層所支持的第2偏光薄膜的光學薄膜20所形成的第2光學薄膜層積體2,來製造光學顯示裝置的層積體6的方法。   [0025] 本方法,雖然是在後述的圖4及圖5或圖6及圖7中被省略的工程,但是其包含:上游工程,即從在液晶面板5的TFT側52的面,層積從第1離形薄膜上與黏著劑層一同被剝離的具有第1偏光薄膜的光學薄膜10的工程開始,該工程的下游工程,為如圖4及圖5或圖6及圖7中詳述的工程,亦即,在層積具有第1偏光薄膜的光學薄膜10的液晶面板5的CF側51的面,以吸收軸成為正交偏光關係的方式,層積從第2離形薄膜上與黏著劑層一同被剝離的具有第2偏光薄膜的光學薄膜20的工程。   [0026] 本方法更可以包含:在液晶面板的CF側51的面層積具有第2偏光薄膜的光學薄膜20的工程中,第2光學薄膜20以不從液晶面板5的長邊之中的1邊側52y露出的方式被層積,以1邊側52y成為相對於液晶面板5的搬送方向平行的方式,朝向將液晶面板5的層積體6進行位置調製的工程而搬送,從層積體6的搬送方向之側方使位置調整機構530抵接1邊側52y,而將液晶面板5進行位置調製的工程、及在該工程後,檢查液晶面板5的層積體6的缺陷等的工程。   [0027] 本方法較佳為在為液晶面板5的CF側51的面層積具有第2偏光薄膜的光學薄膜20的工程中,液晶面板5由CF側51的構件及TFT側52的構件所構成,在1邊側52y,在液晶面板5形成TFT側52的構件從CF側51的構件突出的突出部520,在突出部520的CF側的面521形成端子50,以未覆蓋端子50的方式來層積第2光學薄膜20。   [0028] 本發明在其他的另一個態樣中,提供光學顯示裝置的層積體的製造系統。本發明作為一實施態樣,詳細如同後述,具有圖4的模式圖及圖5的流程圖所示的RTP方式的系統、及圖6的模式圖及圖7的流程圖所示的枚葉型方式的系統。將全體模式地表示的RTP方式的系統如圖2及圖3所示。   [0029] 本發明不管是RTP方式的系統還是枚葉型方式的系統,都是基於以下所示的構成的系統。   具體來說,如圖2及圖3的模式圖所示,本系統為包含:將長方形的液晶面板5搬送的搬送機構300、在被搬送的液晶面板5的一面即TFT側52的面,層積具有對應液晶面板5的寬度或長度的寬度或長度,且具有第1偏光薄膜的光學薄膜10的第1貼合部100、在層積在TFT側52的面具有第1偏光薄膜的光學薄膜10的液晶面板5的CF側51的面,以吸收軸成為正交偏光關係的方式,層積具有比液晶面板5的寬度或長度之中至少一者還大的寬度或長度,且具有第2偏光薄膜的光學薄膜20的第2貼合部200的系統。   [0030] 本系統更可以包含,在第2貼合部200,將層積於液晶面板5的CF側51的第2光學薄膜20以不從液晶面板5的長邊之中的1邊側52y露出的方式層積,以1邊側52y成為相對於液晶面板5的搬送方向平行的方式作搬送的搬送部100、從液晶面板5的搬送方向之側方使位置調整機構530抵接於1邊側52y,而將液晶面板5進行位置調製的位置調整部500、及檢查經位置調整後的液晶面板5的層積體6的缺陷等的檢查部600。   [0031] 本系統較佳為,在第2貼合部200中,液晶面板5由CF側51的構件及TFT側52的構件所構成,在1邊側52y,在液晶面板5形成TFT側52的構件從CF側的構件突出的突出部520,在突出部520的CF側的面521形成端子50,以未覆蓋端子50的方式來層積第2光學薄膜20。[Problems to be solved by the invention]   [0011] The framelessness of optical display devices is achieved by laminating liquid crystals with optical films exposed from the end of the liquid crystal panel in the RTP manufacturing apparatus and manufacturing method After the panel and the optical film, the exposed part of the optical film, that is, the remaining part, is cut away along the end of the liquid crystal panel. [0012] However, as proposed in Patent Documents 2 to 4, in a continuous manufacturing line, when the remaining part of the periphery is cut off after being exposed from the end of the liquid crystal panel and bonded, all the remaining parts are precisely cut off. Cutting off takes time, and productivity is significantly reduced. [0013] Also, for example, according to a customer who has a manufacturing process for liquid crystal panels such as a panel manufacturer, how to cut off the remaining part of the periphery (for example, whether to cut off along the end of the liquid crystal panel, whether to set the number The degree of freedom of the centimeters to expose the belt and cut off, etc.), and the cut off processing of the remaining part of the periphery, are carried out by customers according to their own needs. [0014] Here, it is required that a large amount of the remaining part of the periphery of the liquid crystal panel on which the optical film is exposed and bonded to the liquid crystal panel is not cut away, and the remaining part of the optical film is left to provide a laminated body of the optical display device. . [0015] However, in the RTP method, to provide a laminate without cutting the remaining part of the periphery of the liquid crystal panel and leaving the remaining part of the optical film in a continuous manufacturing line, the liquid crystal panel and the optical film After bonding the liquid crystal panel and the optical film in a state exposed from the four sides on both sides of the liquid crystal panel, when it becomes an optical film with a polarizing film, in order to make the absorption axis of the polarizing film into a cross-polarization relationship, it is confirmed that it becomes a liquid crystal panel The alignment mark of the reference point of the display area becomes difficult. Therefore, the alignment of the liquid crystal panel and the polarizing film becomes difficult. [0016] In addition, the laminated body leaving the remaining part of the optical film becomes unstable because the periphery of the optical film is flexible, and cannot use the position adjustment mechanism that abuts from the side in the conveying direction, and needs to be prepared separately Complex position adjustment mechanism. [0017] All of the manufacturing apparatuses and manufacturing methods of the RTP method described in Patent Document 2 to Patent Document 4, in the manufacturing process or production system, the liquid crystal panel is exposed and bonded, and all the remaining parts of the optical film are cut away The optical display device obtained as a product manufactured in this manner is of course formed of a laminate without an exposed portion of the optical film. [0018] In addition, the embodiments disclosed in Patent Document 3 and Patent Document 4 all disclose only the configuration in which the polarizing film is bonded to the CF side without exposing the polarizing film after being exposed on the four sides on the TFT side, and It does not disclose a configuration in which the polarizing film is first bonded so as not to be exposed on the TFT side, and then exposed on the CF side to bond the polarizing film. [0019] The next technical issue is the same in manufacturing equipment or production system, even if it is provided in response to new customer requirements, only the TFT side is exposed from the four sides, and the polarizing film is laminated and the CF side is not exposed. In the laminated body of the liquid crystal display device in which the polarizing film is bonded, the risk of damage to the terminal on the built-in TFT side cannot be removed when the remaining part of the protrusion is cut away. In addition, when the remaining part is a laminated body with all four sides, it cannot be ruled out that the liquid crystal panel position adjustment mechanism abutting on the front of the inspection section is deformed and the risk of cracks or the like may occur therefrom. The present invention is achieved by challenging this technical subject. [Means to Solve the Problem]   [0020] The above-mentioned problem can be achieved by laminating optical films with polarizing films on both sides of a rectangular liquid crystal panel so that the absorption axis becomes a cross-polarization relationship. The optical film on one side of the liquid crystal panel, that is, the surface on the TFT side, has a width or length corresponding to the width or length of the liquid crystal panel, and the optical film on the other side of the liquid crystal panel, on the CF side, has a width or Any one of the length can be solved by a laminate with a larger width or length. According to this laminate, since the process of cutting off the remaining part of the laminated optical film exposed from the liquid crystal panel can be carried out in a separate device from the continuous manufacturing device, productivity can be greatly improved. In addition, because the laminate of the present invention, the position where the optical film on the TFT side and the optical film on the CF side overlap with the optical film on the CF side has a cross-polarization relationship, and the optical film on the TFT side transmits through the CF side The optical film on the surface of the liquid crystal panel can easily read the alignment mark of the liquid crystal panel and the edge of the liquid crystal panel. Furthermore, since the laminate of the present invention becomes the surface on the CF side of the viewing side when the display device is assembled, an optical film having a width or length greater than at least one of the width or length of the liquid crystal panel is laminated After that, by cutting off the remaining part of the optical film that is exposed and bonded from the liquid crystal panel, the visual side can be made frameless.  [0021] In one aspect of the present invention, a laminate of an optical display device is provided. This is as shown in the schematic diagram of FIG. 1. Specifically, the optical film 10 having the first polarizing film and the optical film 10 having the first polarizing film are attached to both sides of the rectangular liquid crystal panel 5 so that the absorption axis becomes the orthogonal polarization relationship. 2 The optical film 20 of the polarizing film is used as the laminated body 6 laminated. In addition, this is to laminate the first optical film 10 having a width or length corresponding to the width or length of the liquid crystal panel 5 on one side of the liquid crystal panel 5, that is, the surface on the TFT side 52. On the other side of the liquid crystal panel 5, the CF side 51 The laminate 6 of a second optical film having a width or a length larger than at least one of the width or the length of the liquid crystal panel 5 is surface-bonded. The laminate 6 is also laminated so that the second optical film 20 bonded to the surface of the CF side 51 does not protrude from one side 52y of the long sides of the TFT side 52. In the case of this type of laminated body, since the position adjustment mechanism 530 can be brought into contact with one side 52y, the position adjustment of the laminated body 6 can be facilitated. [0022] As can be understood from FIG. 1, the liquid crystal panel 5 is composed of a member on the CF side 51 and a member on the TFT side 52, and the laminate 6 is further on the second optical film 20 on the TFT side 52 of the liquid crystal panel 5 that is not protruding. The long side 52y of the member on the liquid crystal panel 5 is formed with a protrusion 520 on the TFT side 52 that protrudes from the member on the CF side 51, and a terminal 50 is formed on the CF side surface 521 of the protrusion 520, which is attached to the CF side 51 The laminated body 6 in which the second optical film 20 on the surface is bonded so as not to cover the terminal 50 of the protrusion 520. In the case of such a laminate 6, the second optical film 20 is bonded without covering the terminal 50. Compared with the laminate in which the second optical film 20 is bonded to cover the terminal 50, there is no need to add The step of cutting and removing the remaining part of the second optical film 20 covering the terminal 50 will not damage the terminal 50.  [0023] In another aspect, the present invention provides a method for manufacturing a laminate of an optical display device. As an embodiment of the present invention, as described in detail later, it has the RTP method shown in the schematic diagram of FIG. 4 and the flowchart of FIG. 5, and the leaf type shown in the schematic diagram of FIG. 6 and the flowchart of FIG. 7 Way way. Figures 2 and 3 show the RTP method of the whole scheme.  [0024] Regardless of whether the present invention is an RTP method or a leaf-type method, it is a method based on the following configuration. Specifically, as shown in the schematic diagrams of FIGS. 2 and 3, the width or length of the liquid crystal panel 5 corresponding to the width or length of the rectangular shape is used, and the first release film is formed by an adhesive layer. The first optical film laminate 1 formed by the optical film 10 of the first polarizing film supported by the first polarizing film has a width or length greater than at least one of the width or length of the liquid crystal panel 5, and has a second A method of manufacturing a laminate 6 of an optical display device by forming a second optical film laminate 2 formed on the second release film by the optical film 20 of the second polarizing film supported by an adhesive layer . [0025] Although this method is a process that is omitted in FIGS. 4 and 5 or FIGS. 6 and 7 described later, it includes an upstream process, that is, from the surface on the TFT side 52 of the liquid crystal panel 5, lamination Starting from the process of the optical film 10 with the first polarizing film peeled off together with the adhesive layer on the first release film, the downstream process of this process is detailed in Figures 4 and 5 or Figures 6 and 7 That is, on the surface of the CF side 51 of the liquid crystal panel 5 on which the optical film 10 with the first polarizing film is laminated, the absorption axis becomes the orthogonal polarization relationship, and the second release film is laminated with The process of the optical film 20 having the second polarizing film in which the adhesive layer is peeled off together. [0026] The method may further include: in the process of laminating the optical film 20 having the second polarizing film on the surface of the CF side 51 of the liquid crystal panel, the second optical film 20 is not separated from the long sides of the liquid crystal panel 5. One side 52y is laminated so that one side 52y is exposed, and one side 52y is parallel to the transport direction of the liquid crystal panel 5, and is transported toward the process of position-modulating the laminated body 6 of the liquid crystal panel 5. The side in the conveying direction of the body 6 makes the position adjustment mechanism 530 abut on the side 52y to adjust the position of the liquid crystal panel 5, and after the process, inspect the laminated body 6 of the liquid crystal panel 5 for defects, etc. engineering. [0027] In this method, it is preferable that in the process of laminating the optical film 20 having the second polarizing film on the surface of the CF side 51 of the liquid crystal panel 5, the liquid crystal panel 5 is composed of a member on the CF side 51 and a member on the TFT side 52. In the liquid crystal panel 5, a protrusion 520 from which a member on the TFT side 52 protrudes from a member on the CF side 51 is formed on one side 52y, and a terminal 50 is formed on the CF side surface 521 of the protrusion 520 so that the terminal 50 is not covered. In this way, the second optical film 20 is laminated.  [0028] In another aspect, the present invention provides a manufacturing system for a laminate of an optical display device. As an embodiment of the present invention, as will be described in detail later, the system has the RTP method shown in the schematic diagram of FIG. 4 and the flowchart of FIG. 5, and the leaf type shown in the schematic diagram of FIG. 6 and the flowchart of FIG. 7 Way of the system. Figures 2 and 3 show the system of the RTP method that is schematically shown as a whole.  [0029] Regardless of whether the present invention is an RTP system or a leaf type system, it is a system based on the following configuration. Specifically, as shown in the schematic diagrams of FIGS. 2 and 3, the present system includes: a transport mechanism 300 for transporting a rectangular liquid crystal panel 5, and a layer on one side of the transported liquid crystal panel 5, that is, the TFT side 52. The product has a width or length corresponding to the width or length of the liquid crystal panel 5, and the first bonding portion 100 of the optical film 10 having the first polarizing film, and the optical film having the first polarizing film on the surface layered on the TFT side 52 The surface of the CF side 51 of the liquid crystal panel 5 of 10 has a width or length that is greater than at least one of the width or length of the liquid crystal panel 5 so that the absorption axis becomes a cross polarization relationship, and has a second The system of the second bonding part 200 of the optical film 20 of the polarizing film. [0030] The system may further include, in the second bonding part 200, the second optical film 20 laminated on the CF side 51 of the liquid crystal panel 5 so as not to extend from one side 52y of the long sides of the liquid crystal panel 5. Laminated in an exposed manner, one side 52y is parallel to the conveying direction of the liquid crystal panel 5 and the conveying section 100 is conveyed, and the position adjustment mechanism 530 is abutted on one side from the side of the conveying direction of the liquid crystal panel 5 On the side 52y, the position adjustment section 500 that modulates the position of the liquid crystal panel 5, and the inspection section 600 that inspects defects and the like of the laminated body 6 of the liquid crystal panel 5 after the position adjustment.

On the other hand, in the second bonding portion 200, the second optical film 20 laminated on the surface of the CF side 51 of the liquid crystal panel 5 is exposed from the periphery of the liquid crystal panel 5 so that the absorption axis becomes a cross polarization relationship. The liquid crystal panel in which the flexible optical film 20 is exposed and laminated, that is, the transport of the laminated body 6 to the downstream process must also be performed with great care. [0039] In the downstream process of the laminated body 6 produced from the second laminating part 200, at least the laminated body 6 positioned in the position adjustment part 500 is inspected for defects and the like through the inside of the laminated body with a camera device. , And then through the inspection section 600 that reads the alignment mark 53 to inspect the attachment position of the first optical film 10 and/or the second optical film 20 to the liquid crystal panel 5, and the laminate 6 of the optical display device output.

This way is exposed and layered.   [0041] FIG. 4 shows a state in which the first optical film 10 has been laminated on the surface of the TFT side 52 in the upstream process so that the terminal 50 of the protrusion 520 is not exposed. Therefore, step 1 shown in FIGS. 4 and 5 utilizes peeling while winding the carrier film 3 (hereinafter referred to as the second carrier film 3) of the second release film of the second optical film laminate 2 The mechanism 60 peels the second optical film 20 from the second carrier film 3, and protrudes the second optical film 20 only by a predetermined distance. The predetermined distance becomes the bonding start position of the surface of the second optical film 20 on the CF side 51 of the liquid crystal panel 5. In step 2, the front end (or rear end) 20' of the second optical film 20 is specified by the sensor 90 in a protruding state. [0042] As shown in step 3 in FIGS. 4 and 5, the liquid crystal panel 5 on which the first optical film 10 is laminated is sucked and fixed by the liquid crystal panel fixing mechanism 310, and the liquid crystal panel position detection sensor 91 is used to identify After the position of the liquid crystal panel 5 is aligned with the position of the second optical film 20 specified in step 1, the position of the liquid crystal panel fixing mechanism 310 is adjusted.

[0043] In step 5 shown in FIGS. 4 and 5, the front end 5'of the liquid crystal panel 5 is moved to the bonding position 201 by the conveying mechanism 300 of the liquid crystal panel 5. Step 6, the bonding roller 203 and the bonding roller 204 constituting the RTP bonding mechanism 202 sandwich the front end 5'of the liquid crystal panel 5 and the front end 20' of the second optical film 20 slightly inside. [0044] In step 7 shown in FIGS. 4 and 5, while the second carrier film 3 is being wound, the RTP bonding mechanism 202 is activated to laminate the second optical film 20 and the first bonding part 100 The liquid crystal panel 5 with the first optical film 10 is bonded. As shown in FIG. 4, the second optical film 20 is exposed only at a distance α from the short side of the liquid crystal panel 5, and exposed at a distance β from the long side facing the long side of the terminal 50 on which the liquid crystal panel 5 is arranged.

Step 2. After the first alignment stage 701 sucks and fixes the second optical film 20 by the first suction and fixing part 702, the position of the tip 20' of the second optical film 20 is specified by the optical film position sensor 92. [0048] Step 3 shown in FIGS. 6 and 7 coincides with the position of the front end 20' of the second optical film 20 specified, and the position of the leaf-shaped bonding mechanism 703 is adjusted to make the leaf-shaped bonding mechanism 703 The second suction-fixing portion 704 of φ contacts the second optical film 20 side. In step 4, after the second suction and fixing part 704 of the leaf-shaped bonding mechanism 703 is activated, the first suction and fixing part 702 of the first alignment table 701 is released, and the leaf-shaped bonding mechanism 703 is moved. Step 5, in the state of being fixed to the leaf-shaped laminating mechanism 703, the second release film 3'is peeled from the second optical film 20 by a special predetermined mechanism (not shown). [0049] As shown in step 6 of FIG. 6 and FIG. 7, the liquid crystal panel 5 on which the first optical film 10 is laminated is sucked and fixed to the second alignment table 705 by the third sucking and fixing part 706, in a state of a leaf type The liquid crystal panel sensor 707 specifies the position of the liquid crystal panel 5. In the upstream process of the liquid crystal panel 5, the first optical film 10 is laminated on the surface on the TFT side of the liquid crystal panel 5, and the third suction and fixing portion 706 of the second alignment table 705 is sucked and fixed on the TFT side 52 of the liquid crystal panel 5 Noodles.
