ABSTRACT:
A liquid crystal-type nonglare mirror suitable for room mirrors or for vehicles, which effectively prevents the formation of interference fringes under light sources, such as sodium lamps, halogen lamps and the like. The mirror is composed of a transparent electrode base, a liquid crystal and a reflective electrode base, in which the liquid crystal is placed between the above electrode bases. The technical effects may be provided by the limitation that rubbing directions of both electrodes are nonparallel and that the twist angle of the liquid crystal is about 360.degree.. The technical effects may also be obtained from the insertion of a silicon nitride layer in the construction of the mirror.
