titleOfInvention | Liquid crystal alignment film, liquid crystal holding substrate and liquid crystal display device having the same, and liquid crystal alignment film material |
abstract | (57) [Abstract] [Objective] A liquid crystal alignment film, a liquid crystal holding substrate, a liquid crystal display device, and a liquid crystal which can be suitably used for an active type twisted nematic liquid crystal display device and have a high voltage holding ratio and a stable pretilt angle. A material for an alignment film is provided. [Structure] A polyimide containing a structural unit (I) obtained from a tetracarboxylic dianhydride having an aliphatic structure and a diamine, or a structural unit (II) obtained from a tetracarboxylic dianhydride having an aromatic structure and a diamine And the content ratio [(I): {(I) + (II)} of the constituent units] of the polyimide is 0.1 to 1.0, the following formula (III) A liquid crystal alignment film containing the represented imide compound. [Chemical 1] [Wherein, in the formula (III), Y and Z are divalent organic groups which may be different or the same, N and O are mutually bonded to the benzene ring in the ortho position, and n is an integer of 2 to 20. Indicates. ] |
