Abstract
A display device includes: a substrate, a light emitting element which is on the substrate and emits light in a light emitting direction; and a side wall layer including a plurality of light control patterns arranged along the substrate, where the side wall layer is adjacent to the light emitting element in the light emitting direction of the light emitting element. Within the side wall layer which is adjacent to the light emitting element in the light emitting direction, each of the plurality of light control patterns has a certain height, the plurality of light control patterns are arranged along a major surface of the substrate and spaced apart from each other by a certain distance between two adjacent light control patterns of the light control patterns, and a ratio of the height to the distance is greater than about 1.4.
