Abstract:
An active matrix type semipermeable liquid crystal display device comprising an insulator film on a silicon layer forming a source and a drain of a thin-film-transistor, a reflecting electrode formed with surface irregularities on said insulator film in a reflecting section of a pixel, and a transparent electrode made of transparent conductive film on a transparent section of said pixel, wherein an insulator layer between said silicon layer and said reflecting electrode is formed from one layer of insulator film, wherein said transparent conductive film extends to said reflective electrode and said transparent conductive film and reflecting electrode are connected, wherein a protective film is installed between said reflecting electrode and said transparent conductive film, and said cell gap of said liquid crystal display cell is formed by adjusting the thickness of said protective film to Â½&lgr; in the permeable section and set to Â¼&lgr; in the reflecting section of said pixel.
