Abstract

According to the polarizing plate sticking device of the present invention, the first polarizing plate sticking device (600) and the second polarizing plate sticking device (700) are equipped with a four-sided polarizer that can be rotatably arranged around the rotation axis (P11, P12). frame parts (601, 701). Therefore, the work of sticking the polarizers (2, 3) on the liquid crystal cell substrate (1) can be carried out at the polarizer sticking station (S14), and at the same time, the cover film can be removed from the polarizer at the cover film peeling station (S13). The operation of peeling off the sheets (2, 3), and the operation of receiving the polarizing plate (3) at the polarizing plate receiving station (S11). As a result, it is possible to provide a polarizing plate bonding device capable of suppressing an increase in the bottom area of ​​the polarizing plate bonding device due to an increase in the size of a color liquid crystal display.

Description

technical field [0001] The present invention relates to a polarizer sticking device, and relates to a structure of a polarizing plate sticking device capable of suppressing an increase in the bottom area of ​​the device even when liquid crystal cell substrates are increased in size. Background technique [0002] In recent years, color liquid crystal displays are developing toward larger sizes. The mainstream size of color liquid crystal displays has reached 32 inches to 46 inches, and the size of color liquid crystal displays will accelerate toward larger sizes in the future. [0003] first, Figure 8 The cross-sectional structure of the color liquid crystal display 10 is shown. The color liquid crystal display 10 has: a liquid crystal cell substrate 1 made of glass substrates sandwiching liquid crystals, alignment films, transparent electrodes, color filters, etc.; Polarizers 2 and 3 on the second main surface side (CF surface side, TFT surface side). [0004] The manufac...
