DISPLAY DEVICE INCLUDING INORGANIC INSULATING LAYERS

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.
