Abstract

An MVA-LCD(multi-domain vertical alignment LCD)that provides super-high image quality has been developed by newly introduced rubbing-less technology. A newly introduced "protrusion" designed on the TFT stbstrates and on the color filter substrates automatically controls the directors of the LC molecules. By this technology we have successively developed four-domain 15"MVA-TFT units that provide extremely wide viewing angle of more than 160 degrees, a high contrast ratio of 300 : 1 or more and a fast response of less than 25ms.
