Title: LIQUID CRYSTAL DISPLAY ELEMENT AND METHOD FOR PRODUCING SAME
Abstract:
Provided are: a highly reliable liquid crystal display element which is configured to be less susceptible to the occurrence of drip marks during the production without deteriorating various characteristics of liquid crystal display elements such as dielectric anisotropy, viscosity, nematic phase upper limit temperature and rotational viscosity (γ1) and the image burn-in characteristics of liquid crystal display elements, while having various improved characteristics of liquid crystal display elements; and a method for producing this liquid crystal display element. A liquid crystal display element according to the present invention comprises a first substrate, a second substrate and a liquid crystal composition layer that is held between the first substrate and the second substrate. At least one of the first substrate and the second substrate has an electrode; and at least one of the first substrate and the second substrate has an alignment film that contains a polymer having a thermally decomposable group and a polymer of a compound having a polymerizable group which controls the alignment direction of liquid crystal molecules in the liquid crystal composition layer.
