摘要:
A display device includes a substrate; a light-emitting element layer on the substrate; a first thin-film encapsulation layer that is on the light-emitting element layer, has an upper surface conforming an upper surface of the light-emitting element layer, and includes a recessed portion; a bank layer on the first thin-film encapsulation layer and having an opening overlapping the recessed portion; a wavelength conversion layer in the opening on the first thin-film encapsulation layer and at least partially in the recessed portion; a first inorganic layer on the bank layer and the wavelength conversion layer; an organic layer on the first inorganic layer; and a second inorganic layer on the organic layer.
