摘要： A transflective display includes pixels each including a reflective (R) sub-pixel, a transmissive (T) sub-pixel, and electrodes having features to cause multiple domains to form in a liquid crystal layer of the R sub-pixel and the T sub-pixel. The electrodes in the R sub-pixels have features that are different from features of the electrodes in the T sub-pixel to cause the liquid crystal layer in the R sub-pixel to have an optical phase retardation that is between 20% to 80% of an optical phase retardation of the liquid crystal layer in the T sub-pixel. The R sub-pixel and the T sub-pixel have substantially the same cell gap and are driven by the same pixel voltage.

摘要： A liquid crystal display includes pixels, each pixel including a transmissive region and a reflective region. The transmissive region has a liquid crystal layer having a homogeneous alignment, and the reflective region has a liquid crystal layer having a hybrid alignment. In the transmissive region, an alignment layer, a common electrode, and a pixel electrode are on a same side of the liquid crystal layer. In the reflective region, an alignment layer, a common electrode, and a reflective pixel electrode are on a same side of the liquid crystal layer. The alignment layer of the reflective region has an alignment direction that is different from that of the alignment layer of the transmissive region.
