ABSTRACT:
To provide a transflective liquid crystal display device that achieves high-contrast, bright display with a wide viewing angle, a liquid crystal display device includes a liquid crystal layer between a pair of substrates, and also includes dot regions, each having a transmissive display area and a reflective display area. The liquid crystal layer includes negative dielectric anisotropy liquid crystals with homeotropic alignment in an initial state. The reflective display area includes an insulation film to form irregularities on a reflective film. The insulation film is also disposed in the transmissive display area and forms irregularities on one of liquid-crystal contact surfaces of the substrates between which the liquid crystal layer is disposed.
