Multi-domain vertically aligned liquid crystal display

Abstract

A multi-domain vertically aligned liquid crystal display. The multi-domain vertically aligned liquid crystal display has a lower board, an upper board and a liquid crystal. The lower substrate board has a plurality of slits therein. There is a bent protrusion structure on the surface between the slits. The bent protrusion structure has two pairs of surfaces symmetrical about a vertical mid-line. The pair of surfaces next to the slits makes a first angle with the horizontal while the other pair of surfaces next to the mid-line makes a second angle with the horizontal. A thin film transistor is embedded in the lower substrate board underneath the bent protrusion structures for providing an electric field. An indium-tin-oxide electrode is formed on top of each bent protrusion structure. The upper substrate board is mounted on top and parallel to the lower substrate board. The liquid crystal fills the space between the upper and the lower substrate board. The long axes of most of the liquid crystal molecules inside liquid crystal are perpendicular to the upper substrate board. The long axes of most liquid crystal molecules near the slits are perpendicular to the electric field. The long axes of most liquid crystal molecules above the bent protrusion structure deviate from the direction of the electric field by varying degrees.
