ABSTRACT:
A reflective type liquid crystal display device includes: a semiconductor substrate; a transparent substrate having a transparent electrodes; a liquid crystal layer interposed between these substrates; switching elements being formed on the semiconductor substrate correspondingly to a pixel-array; and pixel-electrodes disposed in matrix over the switching elements correspondingly to the pixel-array. Each of the pixel-electrodes is made of a metal selected from a group of materials each generating an electric potential which is substantially the same as an electric potential occurring on each of the transparent electrodes. The reflective type liquid crystal display device is capable of preventing the generation of flicker caused by the battery-effect.
