Abstract: In a display device, a plurality of display panels displaying an image formed by a plurality of pixels are coupled to each other. Each of the display panels includes a display surface having a display region and a non-display region surrounding the display region, and a polarizer provided on the display surface. The polarizer covers the display region and a part of the polarizer extends to the non-display region. A pair of display panels to be coupled to each other are arranged such that parts of the non-display regions overlap with each other. One display panel is located at a display surface side of the other display panel, and the other display panel is located at a rear surface side of the one display panel, the rear surface side being an opposite side to the display surface side.
