摘要： Disclosed is a stereoscopic display device that can reduce moiré that occurs due to light-shielding areas in the aperture of pixels. The stereoscopic display device includes a display panel and a parallax barrier. The display panel has a plurality of pixels and displays a stereoscopic image. In the parallax barrier, the direction in which transmissive and non-transmissive parts are alternately arranged is the first direction and the lengthwise direction of the non-transmissive parts is the second direction. There is a boundary that extends in the second direction between two pixels next to each other in the first direction. There are light-shielding areas in the aperture of each pixel. There is a space between the boundary and the light-shielding areas. Of two pixels next to each other in the second direction, the light-shielding areas in the aperture of one pixel are shifted in the first direction with respect to the light-shielding areas in the aperture of the other pixel.
