Abstract

Pretilt angle effect on the dark-state light leakage and viewing angle of in-plane switching (IPS) liquid crystal display is investigated. As the liquid crystal (LC) pretilt angle increases, the light leakage becomes more severe and the off-axis light leakage from the out-of-plane LC directors cannot be neglected. Introducing an oblique compensation plate (O-plate) reduces the off-axis light leakages from the crossed linear polarizers and the anisotropic LC media simultaneously which, in turn, improves the viewing angle of the IPS LCD.
