Display device and method of fabrication for the same

Abstract

A display device that includes a light emitting element layer disposed on a substrate and including a plurality of light emitting elements and an encapsulation layer including an organic-inorganic hybrid layer disposed on the light emitting element layer, a first inorganic encapsulation layer disposed on the organic-inorganic hybrid layer, a second inorganic encapsulation layer disposed on the first inorganic encapsulation layer, and a third inorganic encapsulation layer disposed on the second inorganic encapsulation layer. The organic-inorganic hybrid layer contains silicon, carbon and nitrogen. The first inorganic encapsulation layer, the second inorganic encapsulation layer and the third inorganic encapsulation layer each contains silicon and nitrogen. An atomic ratio of nitrogen to silicon (N/Si ratio) in the organic-inorganic hybrid layer is greater than an atomic ratio of nitrogen to silicon (N/Si ratio) in the first inorganic encapsulation layer and an atomic ratio of nitrogen to silicon (N/Si ratio) in the third inorganic encapsulation layer.
