Title:
LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2016/140278
Kind Code:
A1
Abstract:
Provided is a liquid crystal display element which has high liquid crystal vertical alignment properties, good optical characteristics, and high adhesion between a liquid crystal layer and a liquid crystal alignment film, and the liquid crystal display element can maintain the characteristics thereof for a long period of time even in an environment where the element is exposed to high temperatures and high humidities or exposed to light. The liquid crystal display element is provided with a liquid crystal alignment film that has a liquid crystal layer obtained by ultraviolet irradiation of a liquid crystal composition which contains a polymerizable compound and liquid crystals and which is disposed between a pair of substrates provided with electrodes, the liquid crystal alignment film being configured so that at least one of the substrates is aligned perpendicularly to the liquid crystals. The liquid crystal alignment film is obtained from a liquid crystal alignment agent that contains component (A) and component (B). Component (A): At least one compound selected from among the group consisting of a compound represented by formula [1-1] and a compound represented by formula [1-2]. Component (B): A polymer having at least one structure selected from among the group consisting of formula [2-1] and formula [2-2].
