Problems solved by technology
Therefore, a redundant area (frame portion) is formed in the peripheral portion of the display area, which hinders the miniaturization of the device.
[0008] In addition, before the optical member is bonded to the liquid crystal panel, dust is suppressed from adhering to the liquid crystal panel by removing static electricity from the liquid crystal panel, but since the bonding surface of the optical member to the liquid crystal panel has adhesiveness, Therefore, dust is easy to adhere to, and there is a problem that it becomes a factor of poor bonding.

[0160] Next, the structure of the film bonding system of 2nd Embodiment is demonstrated. Figure 10 It is a schematic configuration diagram of the film bonding system 2 of this embodiment. exist Figure 10 In , for convenience of illustration, the film bonding system 2 is divided into upper and lower two layers and described. Hereinafter, the same reference numerals are assigned to components common to those of the first embodiment, and detailed description thereof will be omitted.
[0161] In 1st Embodiment, the case where the width and length of the optical member F1X bonded by the bonding roller 32 and the width and length of the display area P4 of liquid crystal panel P were equal was mentioned. On the other hand, the obvious difference between this embodiment and the first embodiment is that it includes a cutting device that, after bonding a single sheet larger than the display area P4 (larger in width and length) to the liquid crystal panel P, then separates the single...

A production system for an optical display device comprises: a first-surface joining device which, for a plurality of the optical display components carried on a line along a prescribed carrying direction, cuts a first optical member sheet at a length corresponding to the long side of a display region in an optical display component while pulling out the belt-like first optical member sheet with a width corresponding to the short side of the display region from a first web roll to form a first optical member, and then joins the first optical member to the optical display component; and a second-surface joining device which cuts a second optical member sheet at a length corresponding to the short side of a display region in an optical display component while pulling out the belt-like second optical member sheet with a width corresponding to the long side of the display region from a second web roll to form a second optical member, and then joins the second optical member to the optical display component for a plurality of the optical display components carried on a line. The direction of an optical display component set to the carrying direction when the optical member is joined to the optical display component in the first-surface joining device is the same as the direction of the optical display component to the carrying direction when the optical member is joined thereto in the second-surface joining device.
Description
technical field [0001] The invention relates to a production system and production method of optical display devices such as liquid crystal displays. [0002] This application claims priority based on Japanese Patent Application No. 2013-031196 for which it applied to Japan on February 20, 2013, and Japanese Patent Application No. 2013-104405 for which it applied in Japan on May 16, 2013, and uses the content here. Background technique [0003] Conventionally, in the production system of optical display devices such as liquid crystal displays, optical members such as polarizing plates bonded to liquid crystal panels (optical display parts) were sometimes cut out from long films to match the size of the display area of the liquid crystal panel. sheets, the individual sheets are bundled and transported to another production line, and then bonded to a liquid crystal panel (for example, refer to Patent Document 1).
