<p>Over a liquid crystal cell (10), there are disposed a phase difference film (30) and an upper polarized light separator (20). Below the liquid crystal cell (10), there are disposed a diffuser (40), a lower polarized light separator (50), a color filter (60), a PET film (70) and an Al evaporation film (80). The upper and lower polarized light separators (20 and 50) are polarized light separators (reflecting polarizers) for reflecting a linearly polarized light in one direction as a linearly polarized light in the one direction and for transmitting a linearly polarized light in another direction perpendicular to the one direction as the linearly polarized light in the other direction. The light from an LED (120) is guided by a light guide (110) into a light guide plate (130) interposed between the upper polarized light separator (20) and the phase difference film (30). The light from the lower face of the light guide plate (130) is emitted toward the liquid crystal cell (10).</p> |
