ABSTRACT:
A liquid crystal display device includes a matrix array substrate, an upper substrate, and a liquid crystal layer sealed between the substrates. The matrix array substrate has a plurality of first display electrodes connected to thin film transistors which are arranged on a substrate, and an insulation film covering the first display electrodes and the thin film transistors. A plurality of second display electrodes are arranged on the insulation film and face the corresponding first display electrodes to form a capacity connection therewith. The second display electrodes are applied with potentials by the first display electrodes. A transmission factor of the liquid crystal layer is variable in accordance with a potential applied between the second display electrodes and a transparent conductive film of the upper substrate.
