Document Type and Number:
WIPO Patent Application WO/2017/221817
Kind Code:
A1
Abstract:
This liquid crystal cell is provided with: a pair of substrates which face each other and have a photo-alignment film on at least one facing surface; and a liquid crystal layer which is interposed between the substrates. This liquid crystal cell is characterized in that: the photo-alignment film contains a polymer which comprises, as the main chain, a polyamic acid that is obtained by polymerizing a tetracarboxylic acid dianhydride having a flexing structure and a diamine compound having an azobenzene group; and the liquid crystal layer contains a first liquid crystal compound having an unsaturated bond and a second liquid crystal compound comprising at least one structure selected from the group consisting of structures represented by chemical formula (1-1) and structures represented by chemical formula (1-2), while having a nematic-isotropic phase transition temperature of 90°C or more.
(Formula 1-1) and (Formula 1-2)
