Abstract:
1. A liquid crystal display device comprising: two substrates; a liquid crystal layer that is sandwiched between the two substrates; and two alignment films, each of the two alignment films being provided on one surface of one associated substrate so as to face the liquid crystal layer, the liquid crystal display device defining multiple picture elements, wherein at least one of the two alignment films is made of a polymer material, the polymer material including: a main chain; an atomic group having a bond that is selectively cut when exposed to an actinic ray; and a side chain that is bonded to the main chain by way of the atomic group, wherein the polymer material with the side chain gives a pretilt angle of greater than 85 degrees but 90 degrees or less to the liquid crystal molecules of the liquid crystal layer, wherein the polymer material without the side chain gives a pretilt angle of 2 degrees to 15 degrees to the liquid crystal molecules of the liquid crystal layer; and wherein the atomic group comprises a benzoyl group.
