A backlight liquid crystal display including a collimated backlight for illuminating a display panel having a liquid crystal layer sandwiched between rear and front polarizers, the panel including an optical refracting film and a diffuser laminated adjacent the front surface of the panel. The refracting film and light scattering diffuser may be either exterior or interior the front polarizer, but on the viewer side of the liquid crystal layer. The optical system of the refracting faceted film along with the diffuser maintains the resolution of the display, improves the contrast ratio over a wide range of viewing angles, reduces its ambient light reflectively, reduces color shifting, substantially eliminates inversion, and enlarges the effective viewing zone of the display.
