Abstract
A liquid-crystal display device having liquid crystal provided between a pair of opposed substrates includes a common electrode formed on a surface of one substrate facing the liquid crystal; surrounding electrodes formed on a surface of the other substrate facing the liquid crystal, the surrounding electrodes provided for defining a plurality of pixel regions, to which surrounding electrodes a potential equal to that of the common electrode is applied; intermediate electrodes formed on the surface of the other substrate, the intermediate electrodes provided for bisecting each pixel region; pixel electrodes formed on the surface of the other substrate for the pixel regions, to which pixel electrodes a potential equal to that of the intermediate electrodes is applied; and gaps formed on the pixel electrodes along the direction in which the intermediate electrodes are arranged, each gap provided for bisecting each pixel electrode in accordance with the width of each intermediate electrode.
