摘要： 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.

摘要： A method of manufacturing a display device includes forming an organic layer on an encapsulation layer disposed on a light emitting layer, forming a slit layer on the organic layer, where a slit exposing at least a portion of a top surface of the organic layer is formed in the slit layer, forming a first trench by performing a primary etching on the organic layer by using the slit layer as a mask, forming a first inorganic protective layer covering a side surface of the first trench, forming a second trench extending from the first trench by performing a secondary etching on the organic layer by using the slit layer as a mask, and forming a light blocking material filling the first trench and the second trench.
