A conventional reflection type liquid crystal display equipment carries out display by reflecting ambient light, so that no backlight is required in a bright environment and the liquid crystal display device is good in power saving characteristic. Even if ambient light is strong in intensity, almost all of the light is absorbed by an absorption type liner polarizer so that only a part of the light reaches the liquid crystal display device. Thus, the reflected light is little and the display is dark. A video image evaluation equipment (10) transforms a circular polarized light projected from acircular polarized light source (12) to a linear polarized light to pass through an absorption type linear polarizer (14) by a wavelength plate (13) and makes the linear polarized light incident on aliquid crystal panel (15). Since the light of the circular polarized light source (12) can be set to be incident on, and to reflect from, the liquid crystal panel (15) without loss, a video image canbe displayed brighter than that of the conventional liquid crystal display device.
