    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: An OLED display device includes a substrate, a first protection layer substrate, conductive lines extending substantially in a first direction, a second protection layer, a first electrode overlapping at least a part of the conductive lines, a pixel defining layer including an opening exposing at least a part of the first electrode, an organic light emission layer, and a second electrode. The opening is divided into a first polygon and a second polygon with respect to an imaginary straight line that passes through the opening at a maximum length in the first direction. A planar area of the first polygon is different from a planar area of the second polygon.
