摘要： An active-matrix liquid crystal display device employing the in-plane switching mode in which an electric field substantially parallel to the substrate surface is applied to the liquid crystals, characterized by weak torsional anchoring of the liquid crystal molecules and the alignment layer surface at the liquid crystal/alignment layer interface to an extent that the extrapolation length which expresses the strength of said torsional anchoring will become not less than 10% of the gap between the substrates. For obtaining such weak torsional anchoring, an organic alignment layer comprising a polymer and/or oligomer having long-chain alkylene and/or fluoro groups, or an inorganic alignment layer formed by oblique evaporation technique, or a photo-reactive alignment layer formed by linearly polarized light irradiation is used.

摘要： In one pixel, a stepped difference portion having an inclination degree a/b is formed on an alignment control layer, the alignment control layer is made of a material in which a liquid crystal alignment capability is given according to a polarization light radiation, and according to the polarization light radiation the liquid crystal alignment capability is added in the vicinity of the stepped difference portion. A thick and transparent organic high molecular layer is interposed between the alignment control layer and a substrate and a close adhesion characteristic and a transparency characteristic can be made compatible therewith. Accordingly, a problem in which the manufacturing margin in an alignment processing is narrow can be solved, and generation of a display failure according to a fluctuation in the initial alignment direction can be reduced. In this way, a large size liquid crystal display apparatus having a high quality and in which the contrast ratio is heightened can be provided.
