Abstract
A guest-host liquid crystal display device has tilted homeotropic orientation using a nematic liquid crystal having negative dielectric anisotropy as a host and a dichroic dye as a guest which is prepared by overcoating an inorganic insulating layer; treating said layer to provide orientation; and treating the layer with a silane surfactant.
Claims7
A guest-host liquid crystal display device having tilted homeotropic orientation using a nematic liquid crystal having negative dielectric anisotropy as a host and a dichroic dye as guest which is prepared by placing the nematic liquid crystal between two glass plates, each of the glass plates, on the surface facing the nematic liquid crystal, having an electrode thereon;
- said electrode having been coated with an inorganic insulating layer;
- said inorganic insulating layer having been treated to provide orientation by being rubbed or polished in a single direction;
- and coating the so-treated layer with a silane surfactant which imparts homeotropic orientation.
