Description of the Invention: The present invention relates to a method of manufacturing a liquid crystal display element and a system for manufacturing a liquid crystal display element. [Prior Art] Patent Document 1 discloses that a plurality of optical films are used for each optical film. A method of manufacturing a liquid crystal display element by sequentially laminating a liquid crystal panel. Specifically, the film is fed from a continuous roll in which a film of an optical film is laminated, and a liner film is left, and the film is cut into a specific size (half-cut) in the film width direction to form a sheet. A material, and a sheet of the release liner is attached to the liquid crystal panel, and a film of the next optical film is sequentially laminated on the optical film laminated on the liquid crystal panel. [Problem to be Solved by the Invention] In the above Patent Document 1, since two or more sheets are sequentially laminated on a liquid crystal panel, Therefore, it is feared that foreign matter or the like will bite into the adhesive. Assuming that a foreign matter or the like is formed, in the next sheet lamination process, a new sheet is further laminated on the liquid crystal panel, and as a result, the yield of the optical film is deteriorated. Further, there is a liquid crystal panel (liquid crystal display element) which optically inspects two layers of an optical film, and the desire to ride is a defect. The liquid crystal display element manufactured by the manufacturing method of the above-mentioned patent 160216.doc 201232097 document 1 is also the same. However, the optical film also has an optical inspection property which lowers the inspection accuracy of the optical inspection. As such an optical ray, for example, a brightness enhancement film such as a reflective polarizing film or a retardation film can be exemplified. Further, in the defect inspection based on the reflected optical image, the reflective polarizing film is estimated to be liable to lower the inspection accuracy according to its characteristics. The present invention has been made in view of the above-described actual circumstances, and in the case of providing a sheet of two or more optical films in a liquid crystal surface concentrating layer, the optical film yield is not lowered, and the optical inspection is not lowered (for example, A method of manufacturing a liquid crystal display element using inspection accuracy of inspection of reflected light and inspection using transmitted light, and a manufacturing system of a liquid crystal display element. The technical means for solving the problem is to solve the above problem. The result of the "repetitive research" is completed. The present invention is as follows: The method for manufacturing a liquid crystal display device of the present invention includes two or more optical, 'n-layered layers v, which includes: a continuous roll in which a lining film of an optical film having a film thickness of a special film containing a binder is wound, and a lining film transporting step of the lining film is carried out; leaving the lining film in the longitudinal direction of the optical film In the film width direction of the positive film, the optical film is cut and formed at a specific cutting interval, and the film forming step of the film is formed; the transfer sub-step of transporting the liquid crystal panel; and the transfer of the liquid crystal panel a liquid crystal panel, wherein the surface of the liquid crystal panel is laminated on the liquid crystal panel side by interposing the above-mentioned adhesive film from the backing film; and the following steps are included; a first sheet laminate step of the sheet I60216doc 201232097; a second sheet stacking step of the sheet of the second area layer optical film of the liquid crystal panel; and the liquid crystal having the surface of the sheet of the optical film formed on both sides panel Line optical inspection of the inspection step; step and after the inspection, on a sheet laminated on the optical film or the first surface of the second surface, the third laminated sheet of the optical film laminate sheeting step. According to this configuration, since the liquid crystal panel can be optically inspected after the two-layer optical film is used, for example, a liquid crystal panel of a good product (normal product) is further laminated with a sheet of another optical film, so that the yield of the optical film can be prevented.

Further, examples of the optical film include, for example, a polarizer and a polarizing film, and the value of the confession of the pancreas is based on a polarizer and a double-sided or single-layer photo-protective film. In addition, there is also a layered surface for protecting the polarized photo or the polarized light m to relieve the surface protective film of the wound. Further, as another optical film, an optical compensation film such as a retardation film and an increase in brightness is exemplified. As the laminated optical film, a retardation film and/or a brightness enhancement film may be laminated on a polarizer or a polarizing film. The polarizing film is exemplified by, for example, a two-color polarizing film. The two-color polarizing film is a step of obtaining a polarizer by (8) drying a polyvinyl alcohol-based film subjected to dyeing, crosslinking, and stretching treatment; (8) a step of bonding a protective layer on one side or both sides of the polarizer. (c) Manufactured by a manufacturing method in which the step of heat treatment is carried out after bonding. The dyeing, cross-linking, and stretching of the polyethylene-based film are required to be carried out simultaneously, and the order of each treatment may be any, as a polyethylene film.

The reflective polarizing film is obtained by laminating a plurality of polymer films A and B of two different materials, for example, by laminating a plurality of layers. In the extending direction, only the refractive index of the material a increases and exhibits birefringence, and the direction in which the refractive index difference of the material AB interface extends is the reflection axis, and the direction in which the refractive index difference does not occur (non-extension direction) becomes the transmission axis.

Further, if necessary, a suitable one of a coating agent such as a lanthanum or a long chain, such as lanthanum fluoride or sulphide, may be used. (Optical film and continuous Xingkun) In the present embodiment, it is not limited to the configuration in which the optical film is formed in a state in which the film is formed, for example, a continuous roll which can be wound in a roll shape. As a continuous roll 160216.doc 14 201232097 For example, (1) an optical film laminate roll-wound having a backing film and an optical film containing a drilling agent formed on the backing film. In this case, the continuous manufacturing system of the liquid crystal display element has a cutting mechanism which does not cut the liner to: 1. The optical film (containing the charm agent) is cut at a specific cutting interval (semi-cut) To form a sheet of an optical film from an optical film. In the cutting, for example, based on the inspection result of the defect inspection device in the continuous manufacturing system, the sheet is made to distinguish the sheet of the good product from the sheet of the defective product. Further, as the continuous roll, for example, (2) an optical film laminate having a liner film and a sheet containing an optical film of an adhesive formed on the liner film, a roll-shaped holder (so-called notched optical) Continuous roll of film). (Liquid Crystal Display Element) The liquid crystal display element is a sheet in which at least one (two colors) polarizing film is formed on one surface or both surfaces of the liquid crystal panel, and a driving circuit is required to be mounted as needed. As the liquid crystal panel, any type such as a vertical alignment (VA) type, a plane conversion (lps) type or the like can be used. The liquid crystal panel 4 shown in Fig. 1 has a configuration in which a liquid crystal layer is sealed between a pair of substrates (a second substrate and a second substrate) which are disposed opposite to each other.

In other words, the step of stacking the second sheet and the second sheet is a step of laminating a sheet of a two-color polarizing film on a sheet of a polarizing film of a liquid crystal panel, and the step of laminating the third sheet is to laminate the surface or the first sheet. In one of the two-sided polarizing film sheets, the transmission axis direction of the sheet of the two color polarizing films is the same as the transmission axis direction of the sheet of the reflective polarizing film.

In the present embodiment, the second sheet accumulating step, the second sheet laminating step, the inspecting step, and the third sheet laminating step are continuously performed. Fig. 1 is a flow chart showing an example of a method of manufacturing a liquid crystal display element. A 2-color polarizing film (SI) is laminated on the surface of the liquid crystal panel (for example, on the visual side). The surface will be specifically described with reference to Fig. 2'. First, the continuous light of the two-color polarizing film is 1 η. armpit? A & soil &<only rare. The two-color partial film and the liner film are sent out from the continuous roll and conveyed to the downstream side (film transfer sub-step, S12). The conveying means is constituted by, for example, a feed roller, a tension roller, a regulating roller, a sensing unit for detecting the feed amount, a control unit for controlling the conveying speed or the feed amount, and the like. The liner film is left, and the two color polarizing films are cut at specific intervals in a film width direction orthogonal to the longitudinal direction of the two color polarizing film to form a sheet of two color polarizing films (cutting step, S13) . As the cutting mechanism, for example, a laser device, a cutter, or the like can be exemplified. The lining film is placed inside, and is folded back at the front end portion of the peeling mechanism, and the sheet of the two-color polarizing film is peeled off from the lining film, and is supplied to the attaching position, and the liquid crystal panel is transported, and the surface is separated from the anodic film by two-color polarized light. The sheet of the film is laminated on the liquid crystal panel side via an adhesive (attachment substep, S14). As the attaching means, for example, a roller for attachment is exemplified. Further, there is a winding sub-step of winding a liner film of the peeled sheet, and a transfer sub-step of transporting the liquid crystal panel to the attachment position. Further, in the transport sub-step, the liquid crystal panel to which the two-color polarizing film is attached is transported to the position % of the next reflective polarizing film. The transport mechanism of the liquid crystal panel is configured by, for example, a control unit for attaching a roller or a transfer roller, a control unit for controlling the conveyance speed or the feed amount, and the like. Next, a two-color polarized light 160216.doc 17 201232097 film sheet (S2) is laminated on the other surface (for example, the back side) of the liquid crystal panel. The sheet of the two-color polarizing film is laminated so that the transmission axis of the sheet of the two color polarizing film laminated in the step and the transmission axis 9〇〇 of the sheet of the two color polarizing film laminated therein are crossed. On the other side of the liquid crystal panel, the liquid crystal panel can be reversed up and down in response to the requirement. In the present embodiment, the two-color polarizing film laminated on the visual side of the liquid crystal panel has a film width direction. The two-color polarizing film laminated on the back side of the liquid crystal panel has a transmission axis in the longitudinal direction orthogonal to the film width direction, so there is no product 90. Rotating the liquid crystal panel can be two colors on a straight line. The polarizing film is laminated on the visual side and the back side of the liquid crystal panel. The surface of the liquid crystal panel will be described again with reference to Fig. 2. The continuous roll (S11) of the two color polarizing film is prepared. The film width wi of the two color polarizing film is preferably larger than the laminated layer. The film width W2 of the reflective polarizing film on the two-color polarizing film is sent from the continuous roll to the downstream side (the film transfer sub-step, s丨2). Film width direction orthogonal to the length direction of the 2-color polarizing film The two color polarizing films are cut at a specific cutting interval L1 to form a sheet of two color polarizing films (cutting step, S 13). The lining film is inside, and the end portion is folded back at the peeling mechanism. The sheet of the color shifting film is peeled off from the lining film and supplied to the attaching position. The sheet of the two-color polarizing film which is peeled off from the lining film is laminated on the liquid crystal panel side while the liquid crystal panel is being conveyed. Attaching the sub-step, S14) Next, the liquid crystal panel having the two-color polarizing film of two-layered layer is inspected (inspection step, S3). The inspection step is based on the liquid crystal panel of the sheet on which the two-color polarizing film is formed on both sides. Obtain the reflected optical image, check the defect (reflective inspection), and image the obtained reflected optical image by 160216.doc -18- 201232097 image analysis, and take the defect. The type and size of the defect taken The quantity is compared with the judgment criterion (proximity value) of the characteristic to judge whether it is a good product or a defective product (the judgment sub-step, S4). If the result of the judgment is good, the sheet of the polarizing film is laminated on the liquid crystal panel ( S5). On the other hand, if the result of the determination is not ', the sheet of the reflective polarizing film is not laminated, and the liquid crystal panel is excluded (excluding step, S6). Hereinafter, the sheet laminated on the two-color polarizing film will be described with reference to FIG. a sheet stacking step of reflecting the polarizing film. The continuous roll G21) for reflecting the polarizing film is prepared. The film width W2 of the reflective polarizing film is preferably smaller than the film width W1 of the laminated two-color polarizing film (see FIG. 4). The polarizing film and the lining film are conveyed from the continuous roll to the downstream side (the film transfer sub-step, S22), leaving the lining film in the film width direction orthogonal to the longitudinal direction of the reflective polarizing film, and the specific cutting interval L2 The reflective polarizing film is cut to form a sheet for reflecting the polarizing film (cutting step, S23). Here, the cutting interval L2 of the reflective polarizing film is preferably smaller than the cutting interval l1 of the two-color polarizing film. (Refer to Figure 4). The film width W2 and the cutting interval L2 of the sheet of the reflective polarizing film are smaller than the film width wi and the cutting interval L1 ' of the sheet of the two-color polarizing film to which the sheet of the reflective polarizing film is attached, respectively. The bonding of the respective sheets is adhered to the inner side of the peeling mechanism, and the sheet of the reflective polarizing film is peeled off from the backing film and supplied to the attaching position. Further, while the liquid crystal panel is being conveyed, the sheet of the reflective polarizing film which is peeled off from the liner film is adhered to the sheet of the two-color polarizing film by the adhesive (attachment step, S24). The attaching mechanism is the same as the above attaching mechanism. The transport sub-step transports the liquid crystal panel to which the reflective polarized light is attached to the next step. In another embodiment of the above-described embodiment, the two-color polarizing film having a transmission axis in the film width direction has a reflective polarizing film having a transmission axis in the longitudinal direction orthogonal to the film width direction, and the liquid crystal panel transport path is configured as In the L shape, after the sheet of the two color polarizing film is laminated on the liquid crystal panel, the liquid crystal panel is transported along the L-shaped transport path, and the sheet of the polarizing film is reflected so that the transmission axis directions are the same direction. The sheet laminated on the two-color polarizing film may be used as the other side of the above-described embodiment on the side of the liquid crystal panel facing the liquid crystal panel, and the sheet of the two-color polarizing film is laminated on the surface side, and secondly, A sheet of two color polarizing films was laminated, and then examined, and then a reflective polarizing film was attached to the sheet of the two color polarizing film laminated on the back side. Further, as another example of the above embodiment, the sheet stacking step further includes a film inspection substep of inspecting the optical film (two color polarizing film and reflective polarizing film), and cutting the inspection result of the sub (four) wire (four) inspection (four), and cutting off The optical film. Further, the cutting sub-step further includes a sub-step of cutting out the optical film of the defective product into a specific size by using the inspection result of the film inspection sub-step (cutting in a manner avoiding the defect (so-called jumping) Cutting)), excluding the sheet of the optical film judged to be defective. Further, the film inspection sub-step can also read the defect information previously attached to the optical film or the liner film, and cut off the defect information based on the defect information. As a defect inspection method, for example, an image generated by transmitting light or reflected light to an optical film is imaged, and the image is subjected to image processing to analyze a defect to determine whether it is a good product or a defective product. Furthermore, the image processing algorithm can be adapted to the method of the fourth method, and the defect can be detected by, for example, '160216.doc 201232097 using the shading of the binarization process. The information on the defect obtained in the defect inspection is connected with the position information (for example, the position coordinate) and transmitted to the control device (not shown), which helps to cut off the sub-step cutting process. Further, as another example, in the film inspection substep, it is preferable to perform inspection of the light film after the liner film is peeled off from the optical film (two color polarizing film or reflective polarizing film), and after inspection, The liner film is adhered to the optical film. Further, in place of the continuous roll of the two-color polarizing film of the above-described embodiment or the continuous roll of the reflective polarizing film, a so-called continuous roll of a notched two-color polarizing film or a continuous roll of a notched reflective polarizing film may be used. In this case, the cutting substep can be omitted. Further, in the above embodiment, the two-color polarizing film (first and second) sheet stacking step, the inspection step, and the reflective polarizing film (third) sheet layer stacking step are successively performed, but the embodiment is not Limited to this. For example, in another embodiment, after the step of laminating the second layer and the step of laminating the second sheet, the step of inspecting and the step of laminating the third sheet may be continuously performed, or the step of laminating the first sheet may be continuously performed. After the second sheet lamination step and the inspection step, a third sheet lamination step is performed. The liquid crystal panel may be housed in the storage portion between the steps that are not continuous. Further, in the above embodiment, the two sheets laminated on one surface of the liquid crystal panel are two-color polarizing film and reflective polarizing film. However, the present invention is not limited thereto, and other optical films may be laminated on the same sheet. The optical film of the third sheet (later) is laminated in the step. 1602I6.doc 21 201232097 (Manufacturing system of liquid crystal display element) A manufacturing system of a liquid crystal display element of an embodiment will be described with reference to Fig. 3 .
