Title:
METHOD FOR PRODUCING LIQUID CRYSTAL PANEL
Document Type and Number:
WIPO Patent Application WO/2017/170070
Kind Code:
A1
Abstract:
The present invention provides a method for producing a liquid crystal panel, which is capable of imparting a liquid crystal molecule with a pretilt angle with use of a horizontal photo-alignment film by a simple process, and which is not susceptible to the occurrence of disclination. A method for producing a liquid crystal panel according to the present invention is a method for producing a liquid crystal panel having a pair of substrates, a liquid crystal layer held between the pair of substrates and a horizontal photo-alignment film arranged between at least one of the pair of substrates and the liquid crystal layer, and comprises a step for forming, on at least one of the pair of substrates, a film that contains a polymer having a specific structure and a step for irradiating the film with S polarized light from a direction inclined to the normal direction of the substrate surface, thereby forming a horizontal photo-alignment film that is obtained by aligning the film. The horizontal photo-alignment film has properties of aligning liquid crystal molecules to be perpendicular to the polarization direction of the light irradiated from the normal direction of the substrate.
