US 2014/0176879 A1 · LIQUID CRYSTAL DISPLAY PROVIDED WITH VIEWING ANGLE COMPENSATION

Abstract

An embodiment of present invention discloses a liquid crystal display provided with viewing angle compensation. The liquid crystal display provided with viewing angle compensation comprises a liquid crystal cell in a vertical arrangement, upper and lower polarizer sheets, and further comprises the first biaxial compensation film provided between the liquid crystal cell and the lower polarizer sheet, the second biaxial compensation film provided between the liquid crystal cell and the upper polarizer sheet, and a monoaxial compensation film provided at the upside and/or downside of the liquid crystal cell. The embodiment of present invention may be applicable for the viewing angle compensation in wide viewing-angle techniques.
