A display device includes a base, a display panel, and a spacer. The display panel is disposed on the base and has a back surface. The back surface has a central area and a peripheral area closer to the edge of the display panel than the central area. The shortest distance between the central area and the base is greater than the shortest distance between the peripheral area and the base. The spacer is disposed between the base and the back surface corresponding to the central area. The spacer is disposed to raise the central portion of the display panel relative to the edge of the display panel, so the arching configuration of the display panel prevents the edge of the display panel from warping.
