Claim 11:
12. A display device comprising:
a substrate;
a pixel electrode;
a pixel-defining layer covering edges of the pixel electrode, an opening of the pixel-defining layer overlapping a portion of the pixel electrode;
an emission layer on the portion of the pixel electrode;
an opposite electrode on the emission layer;
an organic encapsulation layer including a bottom surface facing the opposite electrode and a top surface opposite to the bottom surface;
an inorganic encapsulation layer on the top surface of the organic encapsulation layer; and
a first inorganic insulating layer, a second inorganic insulating layer, and a third inorganic insulating layer that are between the opposite electrode and the bottom surface of the organic encapsulation layer,
wherein the third inorganic insulating layer is directly on the bottom surface of the organic encapsulation layer, the second inorganic insulating layer is between the third inorganic insulating layer and the first inorganic insulating, layer, and the first inorganic insulating layer is between the opposite electrode and the second inorganic insulating layer,
wherein each of the first, second, and third inorganic insulating layers comprises a silicon oxynitride layer, and
wherein the first, second, and third inorganic insulating layers respectively comprise different Si, O, and No content ratios or concentrations.
