The liquid crystal display device includes a liquid crystal panel that includes a pair of substrates, a liquid crystal layer disposed between the pair of substrates, and a pair of polarization plates respectively arranged in the liquid crystal layer on a light incident side and a light emission side, an illumination device that is arranged on the light incident side of the liquid crystal panel and emits light toward the liquid crystal panel, and a light diffusion member that is arranged on the light emission side of the liquid crystal panel and causes light emitted from the liquid crystal panel to be diffused in an azimuthal direction viewed from a normal direction of the liquid crystal panel. When the total width of a polar angle when luminance is reduced to ⅓ of the maximum luminance in characteristics of polar angle luminance of the illumination device is referred to as a ⅓-total width, the ⅓-total width of the illumination device is equal to or greater than 60° in the azimuthal direction in which variations in luminance of the illumination device in a polar angle direction are the greatest.
