Abstract: A display device includes pixels spaced from each other by a first separation distance in a plan view. A transistor is on a base layer. A first organic layer, a second organic layer, and a third organic layer are sequentially located on the transistor. A light emitting element is on the third organic layer and is electrically connected to the transistor. An outermost pixel that is nearest to an edge of the base layer from among the pixels is spaced from the edge of the base layer by a distance within a second separation distance, the second separation distance being less than the first separation distance. At least one of the second organic layer or the third organic layer clads the first organic layer near the edge of the base layer.
