Abstract: A display device having improved reliability includes a substrate including a display area and a peripheral area outside the display area. The display area includes a central display area, a first bending display area contacting the central display area and bent about a first bending axis, and a second bending display area bent about a second bending axis intersecting the first bending axis. The peripheral area includes a corner area rounded and adjacent to the first bending display area and the second bending display area. This display device includes an inorganic layer disposed at the display area and the peripheral area, an opening pattern formed in the inorganic layer and corresponding to the corner area, and a first organic material layer covering the opening pattern.
