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
