    摘要: Homeotropic surface alignment is provided in liquid crystal display cells, utilizing high temperature peripheral sealing material, by fabricating the empty cell prior to introducing a solution of a homeotropic-aligning surfactant dissolved in a volatile solvent. The solvent is evaporated to provide a surfactant film on the cell cavity interior surfaces. The cell is then filled with the liquid crystal material and the cell is sealed.

    摘要: Novel tris-azo dye compositions and a liquid crystal composition containing the tris-azo dye compositions are disclosed. The tris-azo dye composition having terminal aromatic groups has the general formula: ##STR1## wherein R.sub.1 and R.sub.2 are various aromatic compounds including aromatic amines, substituted aromatic amines, hydroxy-substituted aromatic compounds and substituted hydroxy-containing aromatic compounds. When the tris-azo dichroic dyes are used as a guest dye in a host liquid crystal material, they form a novel liquid crystal composition for use in liquid crystal displays. Examples of R.sub.1 and R.sub.2 include organic radicals of aminoquinoline, tetrahydroquinoline, N-ethyl-1-naphthylamine and 1,8-diaminonaphthalene.

    摘要: Self-developing photoresists are developed by exposing the substrate on which they are exposed to a light beam or other energy source which is absorbed by the substrate and which raises the substrate temperature to the thermal decomposition temperature of the overlying photoresist. This exposure may be done through the photoresist layer with a light beam having a frequency to which the photoresist is substantially transparent or may be done from the backside of the substrate using a light beam which is absorbed by the substrate itself if it is sufficiently thin, or by a thin layer disposed on a transparent substrate.

    摘要: Liquid crystal compositions having guest perylene-based dichroic dyes dissolved therein. The perylene dichroic dyes have symmetrically-disposed substituents which are preferably a group forming with the 3,4 and 9, 10 carbons, respectively, a 5 or 6 membered cyclic ring which is substituted by, or fused to, a phenyl ring. The perylene-based dyes of the invention can be used alone or with other compatible dyes as guest dyes to form various colors for coloring the host liquid crystal compositions.

    摘要: Nematic liquid crystal mixtures characterized by a homogeneous boundary condition are prepared by the addition of soluble compounds having at least two polar groups to nematic liquid crystals of either positive or negative dielectric anisotropy. Between approximately 0.5 and 5 percent by weight of compounds such as dicarboxylic acids, aliphatic diamines, aliphatic dinitriles, diols, polyalkylene glycol, alkanol amines, e.g., ethanolamine, diethanolamine, triethanolamine and diethylene triamine, for example, when dissolved in a nematic material produce spontaneous homogeneous boundary conditions therein.
