Brightness-Enhanced Transflective Liquid Crystal Display Having Single-Cell Gap in Vertically Aligned Configuration

摘要

A brightness-enhanced transflective liquid crystal display having a single-cell gap was demonstrated in a vertically aligned (VA) configuration with a patterned retardation layer. The photopatterned retarder was made of a UV-polymerizable liquid crystal (LC) through a single patterning process. The homeotropic LC alignment in the transmissive region and the planar LC alignment in the reflective region were directly produced on the patterned retarder. High reflectance and fast response characteristics were achieved in a single VA transflective LCD with a patterned retardation layer.
