Liquid crystal display and method for manufacturing same

An photo alignment film material for an IPS type liquid crystal display device, adapted to be an alignment control film of a liquid crystal display to drive a liquid crystal with an electric field arising between a pair of electrodes formed on a substrate, comprising a polyamic acid or polyimide that includes cyclobutanetetracarboxylic acid dianhydride and/or its derivative and aromatic diamine;

• and
• wherein the cyclobutanetetracarboxylic acid dianhydride and/or its derivative is a compound represented by a formula [1]:
• where R1, R2, R3, and R4 of the compound of the formula [1] each independently represent a hydrogen atom, a fluorine atom, an alkyl group or alkoxyl group with a carbon number of 1 to 6, with the proviso that at least one of R1, R2, R3, and R4 of the compound of formula [1] is not hydrogen,
• wherein the aromatic diamine compound contains at least one of compounds selected from a group of compounds consisting of ones represented by formulas [2] to [16]:
• where R1, R2, R3 and R4 of the compounds represented by formulas [2] to [16] each independently represent a hydrogen atom, a fluorine atom, an alkyl group or alkoxyl group with a carbon number of 1 to 6, or vinyl group
• {—(CH2)m—CH═CH2, m=0, 1, 2} or a group represented by {—(CH2)n— C≡CH, n=0, 1, 2}, and in the formula [5], X represents a bond group —S—, —CO—, or —NH—.
