Abstract: A display device includes a flexible substrate including a bending area corresponding to an area at which the display device is bent, and a first area and a second area which is spaced apart from the first area by the bending area, a display element unit disposed in the first area of the flexible substrate; and a buffer member disposed in the bending area of the flexible substrate. The buffer member in the bending area includes: a first buffer member having a first maximum thickness, and a second buffer member having a second maximum thickness which is smaller than the first maximum thickness. Among the first buffer member and the second member, the first buffer member disposed closer to the first area and the second member disposed closer to the second area.

Abstract: A display device includes a substrate, a first electrode, an organic light-emitting layer, a second electrode, a phase matching layer, and at least one light-absorbing layer. The substrate includes a plurality of pixel regions and a non-pixel region. The non-pixel region is arranged between adjacent pixel regions. The first electrode is arranged in each pixel region. The organic light-emitting layer is arranged on the first electrode. The second electrode is arranged on the organic light-emitting layer. The phase matching layer is arranged on the second electrode. The at least one light-absorbing layer is arranged on the phase matching layer. A thickness of the second electrode in the non-pixel region is different than a thickness of the second electrode in the pixel regions.
