Abstract: A liquid crystal display device includes a liquid crystal panel that includes a liquid crystal cell including a pair of substrates and a liquid crystal layer sandwiched between the pair of substrates, and a pair of polarizers arranged on a light incident side and a light emission side of the liquid crystal layer; an illumination device that is arranged on the light incident side of the liquid crystal cell, and emits light toward the liquid crystal cell; and a light control member that is arranged on the light emission side of the liquid crystal panel, and controls an emission direction of light emitted from the liquid crystal panel by anisotropically diffusing the light in an azimuthal direction as viewed from a direction normal to the liquid crystal panel. The light control member is arranged such that an azimuthal direction in which a luminance viewing angle of the liquid crystal panel is relatively narrow and an azimuthal direction in which diffusivity of the light control member is relatively high approximately coincide with each other.
