20140354895 | Display Device - A light guide plate receives light emitted from the light source, and emits the light from a light emitting surface. A prism sheet reflects light at a predetermined angle among the light emitted from the light emitting surface, allows the reflected light to enter the light guide plate, and transmits light at another angle. A polarization control element is provided between a 1/4 wavelength plate and a reflection-type liquid crystal display element so as to be parallel to the light emitting surface. The polarization control element splits the light emitted from the 1/4 wavelength plate into first polarized light allowed to transmit as illumination light that enters the reflection-type liquid crystal display element and second polarized light reflected so as to enter the light guide plate, and reflects the light modulated and emitted by the reflection-type liquid crystal display element toward an imaging lens. | 12-04-2014 |
