ABSTRACT:
A normally white twisted birefringent liquid crystal display having first and second retardation films having retardation values of about 80-200 nm on opposite sides of a liquid crystal layer for the purpose of expanding the viewing angles of the display. Also, the viewing zone of this normally white display can be shifted vertically by rotating the optical axes of the retardation films so as to position the viewing zone away from an inversion area.
