Abstract

Serial rolls which are employed in a roll-type lamination system and can prevent deformation of an optical film laminated body are provided, and a manufacturing method and a manufacturing system for a liquid crystal display element are also provided. Serial rolls (R1, R2) are employed in a roll-type lamination system in an environment in which the temperature is 23+-5 DEG C and the humidity is 35 to 80%. The serial rolls (R1, R2) are adjusted in such a way that the moisture content per 1 m2 of optical film laminated bodies (F1, F2) when commencing pulling-out of the optical film laminated bodies (F1, F2) in this environment is no more than 7.8 g. As a result, it is possible to effectively prevent deformation caused by increase in the moisture content of the optical film laminated bodies (F1, F2) which comprise polarization film, until the optical film laminated bodies (F1, F2) are entirely pulled out from the serial rolls (R1, R2).

Description of the Invention: Technical Field The present invention relates to a method and a manufacturing system for manufacturing a continuous roll and a liquid crystal display element. The continuous roll is formed by winding a long optical film laminate. The optical film layering system is characterized in that an optical functional film, an adhesive layer, and a carrier film including at least a polarizing film are laminated in this order, and the continuous roll is used for extracting the optical film laminate and the optical functional film is passed through the adhesive layer. It is attached to the surface of the liquid crystal panel. [Prior Art] The optical functional film attached to the surface of the liquid crystal panel is bundled in a state of being preliminarily punched to have a size corresponding to the liquid crystal panel, and is transported from the optical functional film manufacturer to the panel manufacturer. In the case of an optical functional film containing a polarizing iridium, since the polarizing film is hygroscopic, it is punched, degassed, and bundled in an environment where the humidity is relatively low, and is applied immediately before the liquid crystal panel. The optical functional film is unsealed to prevent degradation of the quality of the polarizing film due to external thirst. In the case of the liquid crystal display element, a method of manufacturing a liquid crystal display element has been proposed. The optical film laminate is taken out from a continuous roll formed by a long optical film laminate, and is formed into a monolithic optical functional film by cutting into a special size. The optical functional film is bonded to the surface of the liquid crystal panel ( For example, Patent Document 2). In such a roll bonding system, even if a continuous report is delivered in a bundled state, Case B "".

In the roll bonding system, the hygroscopic polarizing film is exposed to the air for a long time until the optical film laminate is completely withdrawn from the continuous roll. Therefore, there is a problem in that the water content of the optical film laminate including the polarizing film is increased and deformed, so that the quality of the optical functional film is deteriorated. Further, in the roll bonding system, the liquid crystal panel is held in a system in which a continuous roll is attached, and the optical film laminate which is taken out from the continuous roll is included; the functional film is bonded to the liquid crystal panel in the system. . Due to the presence of a liquid crystal panel [damage due to the influence of static electricity, it is desirable to move the jade liquid crystal panel in a humid environment.] However, in such a humid environment, the humidity is applied around the continuous roller installed in the system. When the temperature is high, the water content of the film laminate is likely to increase, and the quality of the optical functional film due to deformation of the optical layer (10) is likely to be deteriorated. Further, in the optical film laminate wound in a roll shape, since both ends of the wide sound side are always exposed to the air, there is a case where the film absorbs moisture contained in the air, thereby The _(four) volts are in the state of corrugation.

(7) Second inspection step (Fig. i, S13). The defect of the second optical film layered body F2 is inspected using the second defect inspection device. The defect inspection method here is the same as the above-described method using the first defect inspection device 14. However, the approximate inspection step (S3) and the second inspection step (S13) may be omitted. In this case, the defect inspection of the first optical film laminate F1 and the second optical film laminate F2 may be performed at the stage of manufacturing the first continuous roll R1 and the second continuous roll R2.

(8) The second cutting step (Fig.!, S14). The second cutting device 26 cuts at least the second optical function film F21 of the second optical film layered body F2 extracted from the second continuous roll R2. In this example, the second optical film F22 to which the second carrier film F22 is bonded and the surface protective film F23 bonded to the second optical work film F21 are cut without cutting the second carrier film F22. Break into a specific size. However, the configuration is not limited to this. For example, the second optical film layered body F2 may be formed by completely cutting the second optical film layered body. Examples of the cutting mechanism include a laser device, a cutter, and the like. Preferably, it is constructed in accordance with the information of the defect obtained in the second defect inspection device 24 to prevent the defect from being cut. Thereby, the yield of the second optical film layered product F2 is greatly improved. The second optical film laminate F2 containing the defect is configured to be removed by the second discharge device (not shown) without being bonded to the liquid crystal panel W. In the present embodiment, the second optical function film F21' is cut along the length corresponding to the short side of the liquid crystal panel W, but the width of the second continuous roll R2 corresponds to the shortness of the liquid crystal panel | 158521.doc -16 - 201219891 In the case of the side, the cutting may be performed in accordance with the length of the long side of the liquid crystal panel w. The step of transporting the liquid crystal panel w is performed in parallel with the steps of forming the first optical functional film FI 1 and the second optical functional film F21 which are cut as described above. The following processing is performed on the liquid crystal panel W during its conveyance. (9) Cleaning step (Fig. 1, S6). The surface of the liquid crystal panel W is cleaned by grinding, water washing or the like. (1 〇) First optical functional film bonding step (Fig. 1, S5). In the first optical function film F11 that has been cut, the first carrier film F12 is peeled off, and the first optical function film F11 is bonded to one surface of the liquid crystal panel W via the adhesive layer F14 by the first bonding device 18. . At the time of bonding, the first optical function film ρ 11 and the liquid crystal panel W are sandwiched between the pair of rolls facing each other. (11) A second optical functional film bonding step (Fig. 1, S15). In the second optical function film F21 that has been cut, the second optical function film F21 is bonded to the liquid crystal panel W by the second bonding device 28 via the adhesive layer F24. a surface. At the time of bonding, the second optical function film F21 and the liquid crystal panel W are sandwiched between the opposing rollers facing each other. In addition, before the second optical function film F21 is bonded to the liquid crystal panel W, the first optical function film FI1 and the second optical function film F21 are bonded to each other so as to be in the form of orthogonal polarization. The liquid crystal panel after F11 is rotated by 90 degrees by the rotating mechanism 20. However, the configuration is not limited to the configuration in which the liquid crystal panel 胥 is rotated by 90 degrees. The configuration may be such that the first optical film laminate F1 and the second optical film laminate F2 are transported in a direction orthogonal to each other. The functional film F11 and the second optical functional film ρ 21 have a relationship of orthogonal polarization.

Steps (Figure 1, S16). The optical function film F11 and the 卩21 are attached to both sides. The night sunscreen panel W is inspected by an inspection device. As an inspection method, a method of image capturing and image processing using transmitted light and reflected light on both sides of the night Ba panel W is exemplified. Further, as another method, a method of providing a polarizing film for inspection between (10) a camera and an object to be inspected is also exemplified. Further, as an algorithm for image processing, for example, a defect can be detected based on the shading determination by the binarization processing. (13) The liquid crystal panel W, which is judged to be good by the information of the defect obtained in the inspection device, is transported to the subsequent mounting step. When it is determined that it is a defective product, the rework process is performed, and the optical function films F11 and F2 are re-attached and then inspected, and when it is judged to be a good product, the process proceeds to the mounting step, and when it is determined to be a defective product, the process is shifted again. Rework or dispose of. In the above series of manufacturing steps, the liquid crystal display element can be preferably manufactured by making the bonding step of the second optical function film FU and the bonding step of the second optical function film F 2 设为 a continuous manufacturing line. . In the above-described first and second cutting steps, the manner in which the other members of the optical film laminates FI and F2 are cut without cutting the carrier films F12 and F22 (semi-cutting method) has been described. However, it is not limited to such a configuration. For example, a semi-cut continuous roll of a member other than the carrier film F12 and the crucible 22 in the optical film laminates FI and F2 may be used in advance. It is formed by dividing the long optical sheet laminates FI and F2 obtained by cutting the long raw material sheet into a width corresponding to the short side or the long side of the rectangular liquid crystal panel W. Optical Functions Other than Carrier Films F12 and F22 158521.doc • 18·201219891 The films F11 and F21 and the adhesive layers F14 and F24 are wound in a state in which they are cut to have a length corresponding to the long side or the short side of the liquid crystal panel W. The optical film laminates F1 and F2 are taken out from the continuous roll, and the optical functional films F11 and F21 are bonded to the surface of the liquid crystal panel W via the adhesive layers F14 and F24 while being peeled off from the carrier film F12 and F22. Liquid crystal display element. Further, the configuration is not limited to the configuration in which the optical functional films F11 and F21 are cut and then bonded, and may be formed during the bonding process or after the bonding. In the present embodiment, the liquid crystal panel W is bonded to the first optical power b film F11 from above, and the second optical function film F21 is bonded to the liquid crystal panel w from below. However, the liquid crystal panel W may be bonded to the first optical function film fi from below, and the liquid crystal panel W may be bonded to the second optical function film F21 from above. In the case where a mechanism for vertically inverting the liquid crystal panel w after the first optical function film F i is attached is provided, the second optical function film Fu and the second optical power film F21 may be self-contained. The same direction is attached to the LCD panel. In the case of providing a mechanism for vertically inverting the liquid crystal panel W, the above-described rotating mechanism 2 for rotating the liquid crystal panel W by 90 degrees may be provided with an up-and-down reversing mechanism, or may be provided. The liquid crystal panel is a mechanism that rotates 90 degrees while rotating up and down. The polarizing film long optical film laminates F1 and F2 having hygroscopicity are exposed from the continuous rolls R1 and R2 in the roll bonding system as described above, and the optical film laminates FI and F2 are exposed before time. Specifically, the length of β in the air is, for example, preferably 3,000 to 15 Å, and the weight is preferably carried at a speed of 2 to 1 〇 m/min.

When the polarizing film is exposed to the air for a long period of time, there is a problem in that the water content of the optical film laminates F1 and F2 including the polarizing film is increased and deformed, so that the quality of the optical functional films F11 and F21 is deteriorated. Further, as shown in FIG. 2, in the roll bonding system, the liquid crystal panel w is conveyed in a system in which the continuous rolls R1' to R2 are attached, and the optical film laminates F2 and F2 extracted from the continuous rolls R1 and R2 are used. The optical functional films F11 and Ρ21 included are bonded to the liquid crystal panel W in the system. Preferably, the system is disposed inside the partition wall structure D (for example, a clean room), whereby the optical functional films F11 and F21 can be bonded to the liquid crystal panel W in an environment in which the cleanliness is ensured, thereby making it high. Quality liquid crystal display elements. Since the liquid crystal panel W may be damaged by the influence of static electricity, it is preferable to transport the liquid crystal panel W in a humid environment. Therefore, in the present embodiment, the temperature inside the partition wall structure D is set to 23 ± 5 t and the humidity is set to 35 - 80. /.

At the time of 'there is a problem that bubbles are easily generated between the optical functional films FI 1 and F21 at the both end portions and the liquid crystal panel w. Regarding the problem of generating bubbles as described above, the following reasons can be considered. In other words, in the optical film laminates FI and F2 wound in a roll shape, only the moisture contained in the air is absorbed from the surface in the center portion in the width direction, and the both ends in the width direction are both the surface and the end surface. Moisture absorption. Therefore, the moisture absorption amount at both end portions in the width direction of the optical film laminates FI and F2 is larger than the central portion in the width direction. As a result, it is considered that the expansion ratio of both end portions in the width direction of the optical film laminates F1 and ^ is increased, and the both end portions are undulated due to the difference in area, and as a result, bubbles are generated at the both end portions at the time of bonding. The expansion of the polarizing film is mainly caused by the moisture absorption of the polarizing elements F11a and F2la formed of PVA or the like.

Therefore, the continuous rolls R1 and R2 having a larger initial water content are more likely to absorb the shelling direction, and it is presumed that the continuous pro-RJ, which has a larger initial water content, is more likely to absorb moisture at both ends in the width direction. Therefore, the difference in moisture absorption between the central portion and both end portions in the width direction is more remarkable.
