Embodiment Construction

[0045] Next, modes for carrying out the present invention (hereinafter referred to as embodiments) will be described.

[0046] figure 1 It is a perspective schematic diagram of the polarized light irradiation apparatus for photo-alignment which concerns on embodiment of this invention. figure 1 The shown polarized light irradiation apparatus is an apparatus which performs photo-alignment process using the board|substrate S, such as the liquid crystal substrate with a film material, as a workpiece.

[0047] Specifically, figure 1 The device includes: an irradiation unit 1 for irradiating polarized light to a set irradiation region R; stages 21 and 22 on which a substrate S is placed; The stage moving mechanism 3 that irradiates polarized light to the liquid crystal substrate S.

[0048] like figure 1As shown, in this embodiment, two irradiation units 1 are arranged side by side. The direction in which they are arranged side by side is the moving direction of the stages 21 ...

Abstract

A polarized light irradiating apparatus for photo alignment capable of performing a photo alignment process on a plate-shaped member and realizing high productivity is provided. An irradiating unit (1) irradiates an irradiated area (R) with polarized light, and a stage movement mechanism (3) transports first and second stages (21, 22) on which substrates (S) are mounted alternately to the irradiated area (R) and returns the same. A space (L1) larger than a length by which the substrate (S) on the second stage (22) passes through the irradiated area (R) is secured between the first stage (21) positioned at a first substrate mounting-and-collecting position and the irradiated area (R), and a space (L2) larger than a length by which the substrate (S) on the first stage (21) passes through the irradiated area is secured between the second stage (22) positioned at a second substrate mounting-and-collecting position and the irradiated area (R).

Description

[0001] This application is a divisional application of the original application with a filing date of January 23, 2014, an application number of 201410032760.0, and an invention title of "polarized light irradiation device for photo-alignment and polarized light irradiation method for photo-alignment". technical field [0002] The present invention relates to a technique for irradiating polarized light during photo-alignment. Background technique [0003] In recent years, when obtaining the alignment film of the liquid crystal display element represented by a liquid crystal panel, and the alignment layer of a viewing angle compensation film, the technique called photo-alignment which performs alignment by light irradiation is used gradually. Hereinafter, films and layers aligned by light irradiation are collectively referred to as photo-alignment films. In addition, "orientation" or "orientation processing" means giving directionality to some property of an object. [0004]...
