Active-matrix liquid crystal display

摘要

An in-plane switching active-matrix liquid crystal display device includes an alignment layer which is a photo-reactive material layer disposed between a liquid crystal layer and at least one of a pair of substrates of the display device. The display device includes at least one of (a) a tilt angle of 3° or less, (b) an extrapolation length of at least 10% of a gap between the pair of substrates, (c) a torsional anchoring coefficient A2 of an alignment layer surface for liquid crystal molecules at an inner face of the liquid crystal layer and the alignment layer which is not greater than 20 muN/m, and (d) the alignment layer is obtained by using as an acid moiety an acid hydride except for benzophenone tetracarboxylic dianhydride.
