Abstract

A simple wide-view and broadband circular polarizer comprising of a linear polarizer and two uniaxial Alms is proposed to enhance the viewing angle of transflective liquid crystal displays (LCDs). For the transmissive mode, over the entire 90° viewing cone, the normalized light leakage from two stacked circular polarizers is suppressed to below 1.5 × 10-2, and contrast ratio over 10:1 is obtained using a normally black vertically aligned transflective LCD. At the same time, this configuration warrants a broadband operation and reasonably good viewing angle (10:1 contrast ratio is over 40° at all directions) for the reflective mode. The physical mechanisms for achieving broadband operation and wide viewing angle are discussed. © 2008 IEEE.
