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 substrates 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.
