ABSTRACT:
A viewing angle magnification liquid crystal display of this invention comprising: at least a backlight system containing a polarization element (A) obtained by disposing a retardation layer (b) between at least two layers, included in a reflection polarizer (a), and having respective selective reflection wavelength bands of polarized light superimposed on each other to conduct collimation for a diffusion light source; a liquid crystal cell transmitting collimated lights; a polarizing plate disposed on both sides of the liquid crystal cell; and a viewing angle magnifying layer disposed on the viewer side of the liquid crystal cell to diffuse transmitted light. The liquid crystal display can realize a thin type and have a wide viewing angle.
