Abstract: A display device includes a base layer including a plurality of pixel regions, which include a first pixel region, a second pixel region, and a non-pixel region, a pixel defining film disposed on the non-pixel region of the base layer and including a pixel opening disposed corresponding to each of the plurality of pixel regions, and a light-emitting element layer. A valley pattern surrounding a portion of each of the plurality of pixel regions is defined in the pixel defining film and includes a first valley pattern and a second valley pattern. An opening portion is defined at which the valley pattern does not surround the pixel regions and includes a first opening portion and a second opening portion. The first opening portion and the second opening portion do not face each other.
