Multi-Domain Vertically-Aligned LCDs using Circular Polarizers

Abstract

For improving the transmitted light efficiency through a LCD panel, we have theoretically and experimentally studied amorphous and mulit-domain vertically-aligned (VA-) LCDs using two circular polarizers, which combined a linear polarizer with a λ/4 retardation film. From the texture observations, dark regions in the panels were almost perfectly ehnunated by using circular polarizers. And the transmitted light efficiency of a multi-domain VA-LCD panel was improved up to 1.6 times that of a conventional panel configuration, so that the steepness of the electric-optical characteristics was also improved.
