Abstract
A liquid crystal display (LCD) viewable under all lighting conditions without excessive power consumption is described. The LCD comprises a first dichroic polarizer, a second dichroic polarizer, an anti-reflection layer positioned in front of the first dichroic polarizer and a liquid crystal cell positioned between the first dichroic polarizer and the second dichroic polarizer. In addition, the LCD comprises a backlight assembly positioned behind the second dichroic polarizer. Finally, the LCD comprises a diffusing transflector positioned between the backlight assembly and the second dichroic polarizer. The diffusing transflector comprises a diffusing element and a transflective element.
