We invented and successfully fabricated a new multi‐domain vertical alignment (MVA) LCD with high contrast ratio and wide symmetrical viewing‐angle performance. The LCD has a simple fabrication process without rubbing, with no surface protrusion, and no ITO slit geometry. The new MVA LCD makes use of the intrinsic fringe field in each pixel to control the LC alignment, and manifesting 2 domains under column inversion and row inversion, and 4 domains under pixel inversion operation. The viewing angle can be enlarged by the use of optical compensation films, and transmission can be enlarged by improved LC material, drive voltage, pixel design and circular polarizers.
