PROBLEM TO BE SOLVED: To suppress deterioration of an alignment film against light while suppressing manufacturing costs by forming the specified alignment film on a liquid crystal layer side surface of a substrate in a liquid crystal device having liquid crystal interposed between a pair of substrates opposedly disposed. SOLUTION: This liquid crystal device is provided with a TFT array substrate 10 constituting a sample of one transparent substrate and an counter substrate 20 disposed being opposed to the substrate 10 and constituting a sample of the other transparent substrate. And the TFT array substrate 10 is provided with a picture element electrode 9a and an alignment film 16 subjected to a prescribed alignment treatment such as the rubbing treatment is provided on an upper side of the picture element electrode. On the other hand, the counter substrate 20 is provided with a counter electrode 21 over all the surface thereof and an alignment film 22 subjected to a prescribed alignment treatment such as the rubbing treatment is provided on the lower side of the counter electrode 21. Polyimide as an alignment material is applied on the surfaces to film-form the films 16 and 22 and then they are subjected to the rubbing treatment. At this time, aromatic group concentration in the polyimide is specified to be 0-30 wt.%, more preferably 2-25 wt.%. |
