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.
