Abstract
A liquid crystal display device is provided which includes a scattering/transparent liquid crystal cell having a liquid crystal layer for controlling incident light in a scattered or transparent state in accordance with an applied electric field, and a selective reflector arranged on a side of the liquid crystal layer opposite to a side where observation is performed. The reflector has reflecting characteristics to cause light, which has come incident from a direction within a predetermined range of a viewing angle that allows observation of the liquid crystal cell, to reflect in a direction outside the range of the viewing angle on the side where observation is performed.
