Embodiment Construction

[0057] Embodiments of the present invention will be described in detail below with reference to the drawings.

[0058] The substrate 1 according to the embodiment of the present invention is a substrate used to manufacture a substrate for a liquid crystal display panel (or a substrate used to manufacture a liquid crystal display panel). The exposure method according to the embodiment of the present invention is an exposure method for irradiating light energy to the alignment film in a step of aligning the alignment film by a photo-alignment method (=a step of irradiating light energy to the alignment film to align). An alignment film is formed on the substrate 1 according to the embodiment of the present invention, and then an alignment treatment is performed on the formed alignment film by the exposure method according to the embodiment of the present invention. That is, the substrate 1 according to the embodiment of the present invention is a substrate having a configuration...

Abstract

Disclosed are: a substrate in which all of regions to be exposed to light can be irradiated with a light energy with high accuracy; and a light exposure method. Using a light exposure device (5) that is equipped with multiple light exposure units (52) each comprising a light source (521) and a mask (522) having, formed therein, a light-transmissive pattern (5221) that can transmit a light energy emitted from the light source (521), a substrate (1) is irradiated with the light energy through the light-transmissive pattern (5221) formed in the mask (522) while moving the substrate (1) and the light exposure units (52) relatively to each other. At the same time, in one of the light exposure units (52) in which the mask (522) straddles a display region (11a) having a predetermined size and a display region (11b) having a different size from the predetermined size, both the display region (11a) having the predetermined size and the display region (11b) having the different size are irradiated with the light energy using an alignment pattern (12) formed on the substrate (1) as a benchmark for the control of alignment of mask (522).

Description

technical field [0001] The present invention relates to a substrate, an exposure method for the substrate, and a photo-alignment treatment method. Specifically, it relates to a substrate for a liquid crystal display panel or a substrate suitable for photo-alignment treatment among substrates used for manufacturing a liquid crystal display panel, and for the substrate. An exposure method and a photo-alignment treatment method using the exposure method. Background technique [0002] A general liquid crystal display panel includes two substrates for a display panel, and has a configuration in which the two substrates are arranged facing each other with a predetermined minute interval therebetween, and liquid crystal is filled between them. Generally, an alignment film for regulating the alignment of liquid crystals is formed on a substrate for a liquid crystal display panel. The alignment film is formed during the manufacturing process of the substrate for the display panel an...
