Liquid crystal cell and liquid crystal display

A liquid crystal cell comprising:

• a pair of substrates, which face each other and have a photo-alignment film on at least one facing surface;
• and
• a liquid crystal layer interposed between the substrates, wherein
• a liquid crystal material forming the liquid crystal layer contains a liquid crystal compound having a structure selected from the group consisting of chemical formula (1-1) and chemical formula (1-2),
• the photo-alignment film is obtained by subjecting a polymer film including a polyimide polymer having a cyclobutane ring structure to a photo-alignment treatment:
• A1-CnF2n—X1-A2 (1-1)
• A1-X1—CnF2n+1 (1-2)
• in the chemical formula (1-1) and chemical formula (1-2), A1 is a phenyl group, a phenylene group, a naphthyl group, a naphthylene group, a cyclohexyl group, or a cyclohexylene group;
• A2 is a phenyl group, a phenylene group, a naphthyl group, or a naphthylene group, provided that a hydrogen atom in functional groups A1 and A2 is optionally substituted by a fluoro group, a chloro group, a bromo group, a methyl group, or an ethyl group;
• X1 is an oxygen atom or a direct bond;
• and n is an integer of 1 to 6, and
• the photo-alignment film further comprises a (meth)acrylamide polymer.
