Abstract
A patterned vertical alignment (PVA) pixel electrode is disclosed. The PVA pixel electrode includes a first electrode and a second electrode. The first and second electrodes form a pre-tilt angle with respect to a periphery of the pixel. By disposing unequal lengths of indium-tin oxide (ITO) gaps at a periphery of the first and second electrodes, a distance between the first and second electrodes gradually becomes shortened from the center of the pixel outwards. The ITO gaps which are disposed at the periphery of a thin film transistor (TFT)-array substrate and/or a color filter (CF) are adjusted for eliminating a fringe field effect in the present invention, which a transmittance on the pixel regions is improved and an effect of image display quality is enhanced.
