<p>To provide a display for utilizing a transmission polarization variable axis optical element, capable of obtaining a bright image, an upper polarization separator (300) is provided above a TN liquid crystal (140). Between the upper polarization separator (300) and the TN liquid crystal (140), light sources (190) are provided. The light of a linear polarization component (112) parallel to the surface of this paper transmits the upper polarization separator (300). The light of a linear polarization component (123) perpendicular to the surface of the paper is reflected upon the upper polarization separator (300) and advances toward the interior of a liquid crystal display, the resultant light being reflected repeatedly in the liquid crystal display and finally discharged to an observation side through the upper polarization separator (300). Accordingly, a bright image is obtained.</p> |
