ABSTRACT:
A liquid crystal display unit including a plurality of subpixels in each pixel provides superior gradation over a wide viewing angle, and is produced with no increase in manufacturing cost and no deterioration of desired properties (such as reduction in brightness, contrast and response). No additional manufacturing step is required since a control capacitor electrode is formed at the same time as source and drain electrodes constituting a thin-film transistor. By controlling the ratio of display area and the difference in applied voltage of the subpixels, preferable viewing angle properties are obtained. The display properties at the boundary of subpixels are improved by controlling the gap width and the direction of boundary of the subpixels, thus providing a bright display.
