Abstract
A reflective or transflective liquid crystal device employs an internal reflection system including reflecting electrodes serving as reflectors and provided on the side of a substrate, which contacts a liquid crystal, wherein the construction of the device and the manufacturing process therefor are simplified, and a bright high-quality image is displayed. In the reflective liquid crystal device, stripe reflecting electrodes, a transmissive insulating film having a single-layer structure and an alignment layer are provided on a first substrate. The refractive index of the transmissive insulating film is set to be lower than the refractive index of a liquid crystal and the refractive index of the alignment layer. The width of the transmissive insulating film is set to be not less than a first predetermined width with which the reflectance due to multiple reflection by a multilayer film, including the reflecting electrodes, the transmissive insulating film, and the alignment layer is at a maximum for blue light, and not more than a second predetermined width with which the reflectance of the multilayer film is at a maximum for red light.
