Abstract
PURPOSE:To increase the using efficiency of light to perform bright positive display with high contrast by using a colorless and transparent lambda/4 phase difference plate and a metallic reflecting plate with hair pin configuration instead of a polarizing plate. CONSTITUTION:A nematic liquid crystal component with negative dielectric anisotropy which include a dichromatic coloring matter is enclosed between 2 sheets of supporting plates 22 and 23 which have transparent electrodes processed by the vertical grading method after SiO diagonal evaporation and the liquid crystal moleculars are made vertical or inclined against the supporting plates 22 and 23 at no voltage. When voltage is applied, the liquid crystal moleculars are made horizontal 30 to uniform their directors and the components arranged in the direction of director of incident light are absorbed to the long axial direction of coloring matter moleculars 32. A component 33 vertical to the direction of directors is transmitted to penetrate it to a lambda/4 phase difference plate 34, reflect it on a metallic plate 37 with hair line configuration as the projected light 36 of circular polarization 36 with right optical activity, penetrate it into the phase difference plate 34 as a circular polarization 38 with left optical activity and then penetrate it into the liquid crystal layer as a straight polarization 39. The straight polarization 39 is absorbed into the coloring matter sufficiently to obtain a projected light 40 which absorbs color completely.
