Abstract

In a polarizing disc pasting device according to the invention, a first polarizing disc pasting device (600) and a second polarizing disc pasting device (700) are provided with frame components (601 and 701) which are arranged that the components can rotate around the rotating axes (P11 and P12) and have four side surfaces. Therefore while the operation of pasting the polarizing disc (2 and 3) to the liquid crystal unit substrate (1) a the polarizing disc pasting station (S13), the operations of stripping covering thin film from the polarizing disc (2 and 3) at the covering film stripping station (S13) and receiving polarizing disc (3) at the polarizing disc receiving station (S11) can be executed. As a result, the polarizing disc pasting device which can restrain the increasing of the base area of the polarizing disc pasting device caused by the enlargement of the color liquid crystal display device is provided.

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, FIG. 8 shows a cross-sectional structure of a color liquid crystal display 10 . 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 manufacturing pr...
