Abstract

The invention relates to a polarizing sheet sticking device. A first polarizing sheet sticking device (600) and a second polarizing sheet sticking device (700) are provided with frame components (601 and 701) which are rotationally arranged by using rotating shafts (P11 and P12) as centers and are provided with four lateral surfaces. Therefore, when polarizing sheets (2 and 3) are stuck to a liquid crystal unit substrate (1) at a polarizing sheet sticking station (S14), covered films can be peeled from the polarizing sheets (2 and 3) at a covered film peeling station (S13), and the polarizing sheet (3) is accepted at a polarizing sheet accepting station (S11). As a result, the polarizing sheet sticking device which can inhibit the increment of the bottom area thereof due to large size of a color liquid crystal display can be provided.

Description

[0001] This application is a divisional application of the previous application (application date: September 8, 2006, application number: 200680008308.4, invention name: polarizer sticking device). technical field [0002] 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 [0003] 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. [0004] 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 s...
