Projective liquid crystal display device

Abstract

Abstract PURPOSE:To simplify the expansion of a screen and the operation by projecting picture of a liquid crystal picture on a screen through the utilization of a transmission characteristic of a liquid crystal. CONSTITUTION:A liquid crystal panel 3 is arranged as image formation to a light source 1, lenses 2, 4 and a screen 5. The liquid crystal panel 3 is the twisted nematic system and polarized plates 7, 8 sandwiches the panel. The transmittivity is controlled by impressing a voltage to the liquid crystal so as to activate it as a liquid crystal shutter. A color filter 6 is to reproduce a color picture and arranged, e.g., toward the light source side from the polarized plate 7. This system is constituted simply of a light source comprising a lamp or the like, a lens and a screen, and the system is formed compact together with a thin liquid crystal panel.
