Abstract
A multi-domain vertical alignment liquid crystal display (MVA-LCD) panel includes an active element array substrate, an opposite substrate, and a liquid crystal layer disposed between the two substrates. The active element array substrate has scan lines, data lines, active elements, and pixel electrodes formed thereon. Each pixel electrode has first main slits. The first main slits may have a bent configuration. The opposite substrate has a common electrode layer that faces the active element array substrate. The common electrode layer has second main slits. The second main slits may also have a bent configuration.
