Abstract
An object of the present invention is to reduce luminance unevenness caused by interference between a pixel and a PS in a barrier panel without making a design of the PS complicated in a parallax barrier system stereoscopic display device. A plurality of pixels are arranged at a regular pitch in an x direction and a y direction. A light barrier element includes a pair of glass substrates, a liquid crystal layer provided between the glass substrates, and a plurality of PSs provided between the glass substrates. The plurality of PSs are arranged at a regular pitch in the x direction and the y direction. Arrangement pitches of the plurality of PSs in the x direction and the y direction are not integral multiples of arrangement pitches of the plurality of pixels in the x direction and the y direction, respectively.
