摘要： Manufacture of a liquid crystal display is disclosed. The liquid crystal display includes a backlight unit, a backlight unit-side polarizing plate, and a liquid crystal cell held by two glass plates, the liquid crystal cell having an electrode, a liquid crystal layer, an alignment layer, and a color filter arranged between the glass plates. The liquid crystal display also includes a transparent front plate arranged at a side of the liquid crystal cell opposite to the backlight unit, a polarizing plate attached to the liquid crystal cell, and a transparent organic medium layer arranged between the front plate and the liquid crystal cell. Since the front plate is provided at the outermost surface of an image display portion, and the transparent organic medium is filled between the front plate and the liquid crystal module, it is possible to achieve an improvement in wear resistance and a reduction in reflectance.

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.
