Abstract
A light guide plate receives light, which is emitted from a 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 thereamong. Between a ¼ wavelength plate and a reflection-type liquid crystal display element, a polarization control element is provided in parallel to the light emitting surface. The polarization control element splits the light, which is emitted from the ¼ 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.
