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： A liquid crystal display cell being capable of display with liquid crystal molecules aligned towards a predetermined direction has its display characteristics made greatly dependent on the properties of an alignment film coming into contact with the molecules of the liquid crystal. A louver having a predetermined angle is disposed between the substrate on which the alignment film is to be formed and an evaporation material source to pass a material evaporated from the evaporation material for deposition onto the substrate. The thus formed film exhibits a very great orientation controlling power of biaxial anisotropy. This forming method of the alignment film also allows the easy formation of the alignment film on a large substrate.
