Abstract
A display device includes a light emitting structure disposed on a substrate, and a thin film encapsulation layer disposed on the light emitting structure and including an inorganic layer containing silicon oxynitride and an organic layer. A portion of the inorganic layer has a stress intensity factor of about 1.6 MPa or more.
Claims11
A display device comprising:
- a light emitting structure disposed on a substrate;
- and
- a thin film encapsulation layer disposed on the light emitting structure and including an inorganic layer that contains silicon oxynitride and an organic layer,
- wherein a portion of the inorganic layer has a stress intensity factor of about 1.6 MPa or more,
- wherein the inorganic layer includes:
- a first inorganic layer disposed between the light emitting structure and the organic layer and containing silicon oxynitride;
- and
- a second inorganic layer disposed on the organic layer and containing silicon oxynitride,
- wherein the first inorganic layer includes:
- a first barrier layer contacting the organic layer;
- and
- a second barrier layer contacting the light emitting structure,
- wherein the first barrier layer is disposed between the organic layer and the second barrier layer, and
- wherein a number of dangling bonds of the first barrier layer is less than a number of dangling bonds of the second barrier layer.
