A transflective LCD having a patterned retardation layer for a single driving scheme
We have developed a new transflective liquid crystal (LC) display with a single cell gap and a low twisted nematic (LTN) mode configuration. In order to obtain a single cell gap and a single LC mode, we make a patterned retardation layer having both the homeotropic and planar alignment in this display mode. The patterned retardation layer was made of a photo-polymerizable liquid crystalline material by applying single step patterning of a photo-masking technique. The electro-optic characteristics of the transmissive and reflective parts were nearly identical and thus a single driving scheme can be used.
