发明名称 Color liquid crystal display device and method for driving same.
摘要 A color liquid crystal display device comprising light shielding layers (4) and color filters (3) on the inner surface of a cell, wherein similar light shielding layers and color filters are disposed also in a peripheral region outside of a display region which is equipped with groups of striped row and column electrodes (10) opposed mutually to form pixels for display. The respective patterns of the light shielding layers and the color filters are the same in both the display region and the peripheral region. A liquid crystal layer formed in the display device has a twist angle of 160 DEG to 300 DEG , and a retardation compensator composed of a film is superposed on such layer so as to compensate the elliptical polarization. And a non-selective voltage is applied continuously to the scanning electrodes in the peripheral region so as to maintain the peripheral pixels in a light-shielded state, thereby rendering the display easier to be seen. Furthermore, due to overlaps of the color filters and the light shielding layers in both the display region and the peripheral region, the gap between the substrates (8) is retained substantially uniform to minimize the nonuniformity of the backgroud color.
