Abstract
A transflective display device having a single cell gap in which a liquid crystal molecule has at least two pretilt angles. A transparent electrode is formed on the inner surface of the lower substrate, and a reflective electrode is formed on a portion of the transparent electrode, such that a reflective region is over the reflective electrode and a transmissive region is over the transparent electrode, which is not covered by the reflective electrode. The pretilt angle of the liquid crystal molecule in the reflective region is different from the pretilt angle of the liquid crystal molecule in the transmissive region, the reflective region and the transmissive region have the same phase retardation, and the light path through the reflective region is twice the light path passing through the transmissive region.
