| abstract |
In the present invention, the liquid crystal alignment agent contains the compound (X) having a partial structure represented by the following formula (1). □ (in formula (1), R1nAnd R2nIndependently hydrogen atom, halogen atom, cyano group or monovalent organic group, R3nAs a substituent; among them, R1nAnd R2nAt least one of them is a halogen atom, a cyano group or a monovalent organic group; X1nOxygen atom or -NR4n- (where, R4nIs a hydrogen atom, a hydroxyl group or a monovalent organic group, R4nIt can also be bonded to other groups to form a ring structure together with a nitrogen atom). R3nIt can also be bonded to other groups to form a ring structure; n is an integer from 0 to 4; "*" means a bond) |
