ABSTRACT:
A plurality of reflection films are provided behind a liquid crystal layer of a liquid crystal element, corresponding to predetermined regions in the plural pixels Pix. By the regions of the plural pixels wherein the reflection films are provided, reflection parts Pr are formed that reflects the light that enters from the front side and goes out to the front side by the region where the reflection film is provided, and transmission parts are formed that transmits the light that enters from the back side and goes out to the front side by the other regions of the plural pixels. At the same time, color filters, wherein a plurality of apertures are formed to the parts corresponding to the reflection pars Pr of the pixels Pix, are provided respectively corresponding to the plural pixels Pix, and a planarization transparent film covering the aperture is formed on these color filters.
