Abstract

A display device includes a first electrode disposed on a substrate; a pixel defining layer including first through third exposure areas, each exposing at least part of the first electrode; first through third organic light emitting layers disposed in the first through third exposure areas, respectively; a second electrode disposed on the first through third organic light emitting layers; a first capping layer disposed on the second electrode and overlapping upper surfaces of the first through third organic light emitting layers; a second capping member disposed on the first capping layer, does not overlap the upper surface of the first organic light emitting layer, and overlaps only a portion of each of the upper surfaces of the second and third organic light emitting layers; and an encapsulation layer covering the second capping member.

Dependent claims

A display device comprising:

a first electrode disposed on a substrate;
a pixel defining layer including a first exposure area, a second exposure area, and a third exposure area, each exposing at least part of the first electrode;
a first organic light emitting layer, a second organic light emitting layer, and a third organic light emitting layer disposed in the first, second, and third exposure areas, respectively, each of the first, second, and third light emitting layers including an upper surface;
a second electrode disposed on the first, second, and third organic light emitting layers;
a first capping layer disposed on the second electrode and overlapping the upper surfaces of the first, second, and third organic light emitting layers;
