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.
