ABSTRACT:
In a liquid-crystal display (10), unpolarized light from a light source (12) passes through a linear polarization separation layer (14) and strikes a liquid-crystal cell (16). The liquid-crystal cell (16), in response to an applied electrical field, changes the direction of a director, so as to change the direction of the electrical field oscillation vector of the incident linearly polarized light by substantially 0 to 90°, this light then striking a dichroic linear polarization layer (18) on the surface, whereby only a component coincident with the polarization transmission axis thereof is allowed to exit to the outside. The dichroic linear polarization layer (18) transmits 50% of this incident light, and absorbs the remaining 50%.
