Manufacturing method of liquid crystal element and liquid crystal alignment agent

Abstract

A method for manufacturing a liquid crystal element includes the following steps: coating a liquid crystal alignment agent onto the respective conductive films of a pair of substrates having conductive films to form a coating; arranging the pair of substrates with the coatings formed thereon in a manner that the coatings face each other to construct a liquid crystal cell; and irradiating the liquid crystal cell with ultraviolet light from an ultraviolet LED light source while a voltage is applied between the conductive films, wherein the liquid crystal alignment agent contains a polymer (P) that contains structural units derived from aliphatic tetracarboxylic acid derivatives.
