Abstract: A display device includes: a substrate; a first electrode on the substrate; a bank layer partially exposing a top surface of the first electrode; a light emitting layer disposed on the partially exposed top surface of the first electrode; a second electrode on the light emitting layer and the bank layer; an inorganic deposition layer on the second electrode; and a thin film encapsulation layer on the inorganic deposition layer, where at a wavelength of about 550 nm, an absorption coefficient (k) of the inorganic deposition layer is less than about 4.
