Abstract
A liquid crystal display device includes a liquid crystal panel, a pair of polarizing layers, a lighting device, and an output angle control member. The liquid crystal panel includes a pair of substrates, and a liquid crystal layer. The liquid crystal layer is interposed between the pair of substrates. The pair of polarizing layers is arranged on a light input side and a light output side of the liquid crystal layer. The lighting device is arranged on the light input side of the liquid crystal panel and radiates light toward the liquid crystal panel. The output angle control member is arranged on the light output side of the liquid crystal panel and controls an output angle of light which is output from the liquid crystal panel. An azimuth angle direction in which a view angle of the liquid crystal panel is relatively narrow and an azimuth angle direction in which an intensity of light which is radiated toward the liquid crystal panel from the lighting device is relatively small approximately match in an azimuth angle direction which is viewed from a direction normal to the liquid crystal panel.
