Abstract:
An alignment film material according to the present invention includes: a precursor of a first polyimide (p1); a second polyimide (p2) and a precursor thereof; and a vinyl-type monomer. The vinyl-type monomer is represented by general formula (1) P1-A1-(Z1-A2)n-P2 (in general formula (1), P1 and P2 are, independently, acrylate, methacrylate, acrylamide or methacrylamide; A1 and A2 represent, independently, 1,4-phenylene, 1,4-cyclohexane or 2,5-thiophene, or naphthalene-2,6-diyl or anthracene-2,7-diyl; at least one of A1 and A2 is substituted by at least one fluorine group; and Z1 is a —COO— group, a —OCO— group, a —O— group, a —CONH— group or a single bond, where n is 0 or 1).
