(57) [Abstract] [PROBLEMS] To provide a liquid crystal device using a polymer-based liquid crystal alignment film, which has a small residual charge or a high voltage holding ratio. [Configuration] In a liquid crystal device using a polymer-based alignment film, At least one compound selected from the group consisting of polyacrylic acid alkyl ester, polymethacrylic acid alkyl ester, copolymers thereof, polyoxyethylene glycol di (meth) acrylate, and polyoxypropylene glycol di (meth) acrylate. A liquid crystal element obtained by using as the second component, an alignment film material containing 0.01 to 10% by weight with respect to the polyimide precursor material as the main component. The liquid crystal device of the invention can reduce the residual charge while improving or maintaining the voltage holding ratio. |
