Abstract:
Displays having narrow viewing angles that can be fabricated using fabrication facilities geared toward wide angle displays are described. In one display, a narrow viewing angle optical film is placed between the LCD panel and the polarizers. The narrow viewing angel optical films have a vertically orientated optical axis and a positive birefringence.
