Abstract

A display panel includes a light-emitting element and a capping layer disposed at a light exit side of the light-emitting element. The light-emitting element includes a first light-emitting element, a second light-emitting element and a third light-emitting element emitting a first color light, a second color light and a third color light, respectively. The capping layer includes a first capping layer and a second capping layer stacked together. The second capping layer includes a first sub-capping layer, a second sub-capping layer and a third sub-capping layer correspondingly disposed at light exit sides of the first light-emitting element, the second light-emitting element and the third light-emitting element, respectively. At least one of the first sub-capping layer, the second sub-capping layer, or the third sub-capping layers is configured to have a larger refractive index of light emitted by the corresponding light-emitting element than light emitted by other light-emitting elements.
