Abstract: A display device includes a first display substrate, a second display substrate, and a sealing member. The first display substrate includes a first base layer. The second display substrate includes a second base layer including pixel regions and a peripheral region, and color filters, and is disposed on the first display substrate. The sealing member is interposed between the first display substrate and the second display substrate. The first display substrate includes light emitting elements overlapped with the pixel regions, respectively, an encapsulation layer to cover the light emitting elements, a split pattern including openings overlapped with the pixel regions, respectively, and disposed on the encapsulation layer, and light control patterns disposed in the openings. An end portion of an organic layer of the encapsulation layer, which is overlapped with the non-display region, is covered by the split pattern.

Abstract: A display panel includes a light emitting element that outputs source light and that includes a first electrode, an emissive layer over the first electrode, and a second electrode over the emissive layer and a light control layer over the light emitting element. The light control layer includes at least one light control pattern and a barrier layer that is on one surface of the light control pattern and that contains silicon oxynitride (SiON). The barrier layer contains 0.1 atomic% to 18 atomic % nitrogen, 42 atomic% to 70 atomic% oxygen, and 25 atomic% to 45 atomic% silicon. Accordingly, the durability and barrier characteristics of the barrier layer and the light conversion efficiency of the light control pattern may be improved, and thus the reliability and display efficiency of the display panel including the barrier layer and the light control pattern may be enhanced.
