Abstract
A liquid display panel having minute unit liquid crystal cells, liquid crystalline molecules present in a plane passing the thicknesswise middle points of the unit liquid crystal layer and parallel to the substrate oriented substantially uniformly in all directions and at least one polarization plate, the aforementioned liquid crystal is a nematic liquid crystal material having a positive permittivity anisotropy, so that a wide viewing angle liquid crystal display panel enables high contrast and uniform display of a liquid crystal panel without a rubbing treatment.
Claims12
A liquid crystal display panel comprising a liquid crystal layer between a pair of transparent electrode substrates and at least one polarizing plate disposed outside said transparent electrode substrates, wherein
- said liquid crystal layer has unit liquid crystal cells partitioned by steps each having a height lower than the thickness of said cells;
- liquid crystal molecules in each of said liquid crystal cells are oriented parallel to surfaces of said substrates when an electric field is not applied;
- and
- said liquid crystal layer has domains in which said liquid crystal molecules are oriented at random.
