Abstract

Provided is a method for sticking a polarizing plate to a liquid crystal panel particularly suitable for sticking the polarizing plate to the large size liquid crystal panel by mounting a polarizing plate sticking unit on a conveyance line of the liquid crystal panel, thus adopting a structure with no stage and saving space and making the structure compact as far as possible. A device for sticking the polarizing plate is constructed in such a way that a release sheet E of the polarizing plate B is released so as to expose an adhesive layer and subsequently the polarizing plate B is stuck to a substrate A while transferring the substrate A such as the liquid crystal panel along the conveyance line 2 in one direction from the carry-in side to the carry-out side.

Description

technical field

[0001] The present invention relates to a method and apparatus for bonding a polarizer to a substrate, and more particularly to a method for bonding a polarizer to a substrate, such as a liquid crystal panel, using an adhesive layer when peeling off a separator sheet. Methods and Apparatus. Background technique

[0002] Generally, a liquid crystal panel is obtained by sealing liquid crystal in a space in a liquid crystal cell formed between opposing surfaces of two glass substrates, and by bonding a polarizer to each of the two glass substrates of the liquid crystal panel. Manufactured on the outside.

[0003] The polarizer has a laminated structure in which a polarizing film for polarizing light is used as a base material, one surface of the polarizer is coated with a protective film, and an adhesive applied on the other surface is protected by a separator.

[0004] In the method of manufacturing a liquid crystal panel, the polarizer is adhered to an outer...

Embodiment Construction

[0066] Embodiments of the present invention will be described below with reference to the drawings.

[0067] figure 1 The general structure of the device in which the polarizer is bonded to the liquid crystal panel (substrate) is shown. The transmission line 2 of the liquid crystal panel A is horizontally arranged in the upper part of the support stand body 1 . The conveying line 2 is a conveying path for a liquid crystal panel, in which a roller conveyor 2a on the input side, a roller conveyor 2b on the output side, and a polarizer B arranged at a predetermined interval between the roller conveyors 2a and 2b The bonding sites 3 are arranged in a straight line. The polarizer bonding unit 5 is arranged at a position just below the bonding position 3 . The vertically movable pressure roller mechanism 6 is arranged at a position just above the gluing station 3 . The separator peeling unit 7 is arranged at a position below the roller conveyor 2 a on the input side.
