    Abstract: A display device includes a substrate, a partition wall disposed on the substrate and having a plurality of openings, a first emission layer, a second emission layer, and a third emission layer respectively disposed in an opening of the partition wall and emitting light of different colors, a light blocker disposed on the emission layers and including a plurality of openings respectively overlapping the first emission layer, the second emission layer, and the third emission layer, and a color filter disposed in the opening of the light blocker. A separation distance between one edge of the partition wall contacting the second emission layer and the light blocker is greater than a separation distance between the one edge of the partition wall contacting the first emission layer and the light blocker.

    Abstract: A display device includes: a base layer; a pixel defining film on the base layer; a light emitting element including a light emitting layer in an opening in the pixel defining film; a capping layer on the light emitting element; and an encapsulation layer on the capping layer. The encapsulation layer includes: a first optical layer on the capping layer; a second optical layer on the first optical layer; and a stabilization layer on the second optical layer. A thickness of the stabilization layer is greater than a thickness of the first optical layer and a thickness of the second optical layer. A refractive index of the capping layer is higher than a refractive index of the first optical layer, and a refractive index of the second optical layer is higher than the refractive index of the first optical layer and a refractive index of the stabilization layer.

    Abstract: A display device includes a display panel and a color filter. The display panel includes a light emitting element, an organic capping layer having a first refractive index, and a thin film encapsulation layer. The thin film encapsulation layer includes a first inorganic insulating layer, having a second refractive index, disposed directly on the organic capping layer, a second inorganic insulating layer, having a third refractive index, disposed directly on the first inorganic insulating layer, a third inorganic insulating layer, having a fourth refractive index, disposed directly on the second inorganic insulating layer, an organic layer disposed directly on the third inorganic insulating layer, and a fourth inorganic insulating layer disposed directly on the organic layer. The first and third refractive indices are each greater than the second refractive index, and the second and fourth refractive indices are each smaller than the third refractive index.

    Abstract: A display device includes a lower substrate, a planarization layer, a first light emission structure, and a second light emission structure. The lower substrate includes a first region and a second region. The planarization layer is disposed on the lower substrate, and has a first thickness in the first region and a second thickness, which is less than the first thickness, in the second region. The first light emission structure is provided in the first region and arranged on the planarization layer, and emits a first color of light. The second light emission structure is provided in the second region and arranged on the planarization layer, and emits the first color of light.
