ABSTRACT:
In a liquid crystal display device having a transmissive display region and a reflective display region within a unit pixel, the present invention disposes an optical reflection layer having an almost rectangular planar shape as extended in the unit pixel elongate direction at substantially a central portion midway between two neighboring signal electrodes, defines almost rectangular regions between the optical reflection layer and two signal electrodes adjacent thereto as the transmissive display region in the unit pixel, and forms a pixel electrode at a level spaced from that of the optical reflection layer by a dielectric film so as to cover the entire surface of the unit pixel, so that power consumption of the liquid crystal display device is reduced while image quality thereof is improved.
