Abstract: A light emitting display device includes: a substrate; an organic film on the substrate; a green light emitting diode on the organic film and including a first anode; a red light emitting diode on the organic film and including a second anode; a black pixel defining film having an opening exposing the first anode and an opening exposing the second anode; a cathode on the black pixel defining film, the first anode, and the second anode; an encapsulation layer covering the cathode; a light blocking member on the encapsulation layer and having an opening; and a color filter filling the opening in the light blocking member. A portion of the organic film overlapping the first anode in a plan view has a halftone exposure area, and a step of the halftone exposure area is 30 nm or less.

Abstract: 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.
