Patent ID: 8679595

Claim:
A liquid crystal display device comprising: an active matrix substrate having a pixel electrode; a counter substrate having a counter electrode; vertical-alignment type liquid crystal layer provided between the active matrix substrate and the counter substrate; and alignment sustaining layers provided between the active matrix substrate and the liquid crystal layer and between the counter substrate and the liquid crystal layer, the alignment sustaining layers containing a polymerization product resulting from polymerization of a polyfunctional monomer, wherein, at least one of the active matrix substrate and the counter substrate further includes an alignment film; the alignment film contains polyimide and a polymerization product resulting from polymerization of another polyfunctional monomer; wherein the polyfunctional monomer of the polymerization product contained in the alignment film is represented by general formula (1) Pb1-Ab1-(Zb1-Ab2)n-Pb2 (in general formula (1), Pb1 and Pb2 are, independently, acrylate, methacrylate, acrylamide, or methacrylamide; Ab1 and Ab2 represent, independently, 1,4-phenylene, 1,4-cyclohexane or 2,5-thiophene, or naphthalene-(2,6)-diyl or anthracene-(2,7)-diyl; and Zb1 is a —COO— group, a —OCO— group, a —O— group, a —CONH— group or a single bond, where n is 0 or 1); and wherein at least one of Ab1 and Ab2 is substituted by at least one fluorine group.
