Transflective LCD with tilting direction of the LC molecules being opposite to each other in the two transmissive display areas
摘要:
The invention provides a transflective liquid crystal display device that has less defects, such as incidental images both in reflective display and transmissive display modes, and that has high luminance and high contrast. The liquid crystal display device according to the invention can include a liquid crystal layer sandwiched between a pair of substrates. Each dot area of the display device has a reflective display area and at least two transmissive display areas. The liquid crystal layer can include liquid crystal with negative dielectric anisotropy. The initial alignment state of molecules of the liquid crystal is vertical. An adjusting layer is provided between the liquid crystal layer and one substrate of the pair of substrates. The adjusting layer makes the thickness of the liquid crystal layer different in the reflective display area and the transmissive display area and is provided in the reflective display area. The tilting direction of the liquid crystal molecules is opposite to each other in two adjacent transmissive display areas and the liquid crystal molecules in the reflective display area are in parallel.
