摘要： A transflective liquid crystal display device having excellent display quality is provided which is capable of precisely controlling the alignment of liquid crystal molecules and of providing a high brightness display both in a transmissive display mode and in a reflective display mode. The transflective liquid crystal display panel has a pair of substrates, a liquid crystal layer sandwiched between the substrates, pixel electrodes disposed on the surface of one of the substrates facing the liquid crystal layer, a counter electrode disposed on the surface of the other substrate facing the liquid crystal layer, and an alignment film covering the surface of each of the substrates facing the liquid crystal layer. The pixel electrodes, each including an electrode for reflective display and an electrode for transmissive display, are disposed such that the distances to the other substrate from the electrode for reflective display and from the electrode for transmissive display are different. Liquid crystal molecules at the liquid crystal layer surface facing the electrode for reflective display in a region above the electrode for reflective display (reflective display region) are aligned in the same direction as liquid crystal molecules in a region above the electrode for transmissive display (transmissive display region) that are in the same plane as the molecules in the reflective display region, the plane being parallel to the principal surfaces of the substrates.
