Patent ID: 7106404

Claim:
A liquid crystal display device, comprising: a pair of substrates; a liquid crystal layer disposed between the pair of substrates; and dot regions each having a transmissive display area for transmissive display and a reflective display area for reflective display, the liquid crystal layer including negative dielectric anisotropy liquid crystals with homeotropic alignment in an initial state, the reflective display area including a light-diffusing device to diffuse reflected light, and the transmissive display area including a liquid-crystal-contact-surface-roughness-forming device to form irregularities on one of liquid-crystal contact surfaces of the substrates between which the liquid crystal layer is disposed, the irregularities determining tilt of the liquid crystals based on changes in an electric field applied to the liquid crystal layer, and the light-diffusing device and the liquid-crystal-contact-surface-roughness-forming device being formed of the same material.
