Abstract
A display device includes a organic light emitting device and an encapsulation structure disposed on the organic light emitting device that seals the organic light emitting device. The encapsulation structure includes a first inorganic encapsulation layer disposed on the organic light emitting device, an organic layer disposed on the first inorganic encapsulation layer, and a second inorganic encapsulation layer disposed on the organic layer. The organic layer includes a first organic layer disposed on the first inorganic encapsulation layer and a second organic layer disposed on the first organic layer. An atomic ratio of carbon to silicon in the first organic layer is less than an atomic ratio of carbon to silicon in the second organic layer.
