In TN LCD the retardation of LC is not the same in different viewing angle so that one might see the grayscale inversion. In multi-domain vertically aligned LCD the retardation is always the same in different viewing angle because of the self-compensation of the liquid crystal alignment so that there is no grayscale inversion.

The conventional MVA technology has smaller viewing angle in the azimuth angle of 45 degree.

The viewing angle of MVA LCD is increased to 80 degree in all azimuth angle by CMO’ Super MVA technology.
