| titleOfInvention | Liquid crystal display device and manufacturing method thereof |
| abstract | (57) [Abstract] [Purpose] An object is to provide a liquid crystal display device having a wide effective viewing angle and few display abnormalities. A liquid crystal display device comprising a liquid crystal cell in which liquid crystal is filled between a pair of substrates each having an alignment film formed on a surface thereof, wherein a plurality of liquid crystal display devices having different alignment orientations or rising directions of liquid crystal molecules formed in a display screen are provided. Of the alignment film material, a polyimide having a glass transition temperature of 300 ° C. to 400 ° C., a polyimide having no two-rotational symmetry axis in the skeleton, and a non-conjugated carbon forming an imide bond in the skeleton. Polyimide occupying 10 to 60% of the total number of carbons removed, 20 ° C A polyimide having a relative dielectric constant of 4 to 7 at a frequency of 1 kHz, a polyimide in which a tetracarboxylic dianhydride portion does not cause free rotation, and a polyimide having an imidization ratio of 90% or more. It is characterized by having done. |
