摘要： A display device includes: a substrate; a display element on the substrate; a capping layer on the display element; an optical layer on the capping layer, and including: a first optical layer on the display element; and a second optical layer on the first optical layer; and a thin film encapsulation layer on the optical layer, and including: a first inorganic encapsulation layer on the second optical layer; an auxiliary layer on the first inorganic encapsulation layer; an organic encapsulation layer on the auxiliary layer; and a second inorganic encapsulation layer on the organic encapsulation layer. A refractive index of the second optical layer is smaller than a refractive index of the capping layer, and a refractive index of the first optical layer is between the refractive index of the second optical layer and the refractive index of the capping layer.

摘要： A display device includes a light emitting element including a pixel electrode, a light emitting layer, and a common electrode. A capping layer is disposed on the common electrode. An auxiliary layer is disposed on the capping layer. A thin film encapsulation layer includes a first encapsulation layer, a second encapsulation layer, and a third encapsulation layer. The first encapsulation layer includes a first inorganic insulating layer including silicon nitride; a second inorganic insulating layer including silicon oxide; and a third inorganic insulating layer including silicon oxynitride. The auxiliary layer has a thickness of 200 Å to 1400 Å, the first inorganic insulating layer has a thickness of 400 Å to 3500 Å, the second inorganic insulating layer has a thickness of 200 Å to 2400 Å, and the third inorganic insulating layer has a thickness of 4000 Å or more.

摘要： A display device includes a first substrate including a pixel region and a peripheral region at least partially surrounding the pixel region and a plurality of pixels disposed in the pixel region. The plurality of pixels includes first, second and third sub-pixels each having a light emitting region. The display device further includes light emitting elements respectively disposed in the light emitting regions of the first to third sub-pixels and a color conversion layer having color filter patterns corresponding to respective light emitting elements. At least one of the color filter patterns has a size smaller than that of the light emitting elements in a first direction of the first substrate, and the rest of the color filter patterns has a size larger than that of the light emitting elements in the first direction of the first substrate.
