ABSTRACT:
Disclosed is an active matrix liquid-crystal display, which has: two transparent insulative substrates, either one of which having a plurality of scanning lines, a plurality of signal lines formed in the direction of intersecting with the plurality of scanning lines, a plurality of switching elements disposed on the intersection points of the plurality of scanning lines and the plurality of signal lines, and pixel electrodes connected to the plurality of switching elements; a liquid crystal sandwiched between the two transparent insulative substrates; polarizing plates disposed outside the two transparent insulative substrates; and linear opposing electrodes formed, through insulating film, under the pixel electrodes with a width greater than that of the pixel electrode; wherein the liquid crystal has positive permittivity anisotropy and is oriented nearly perpendicularly to the transparent insulative substrates, the pixel electrode is composed of single or a plurality of linear electrodes, and the direction of the liquid crystal is controlled by electric field to be formed between the pixel electrode and the opposing electrode.
