Abstract: A display device includes a light emitting element including a pixel electrode, a light emitting layer, and a common electrode. A capping layer is disposed on the common electrode. An auxiliary layer is disposed on the capping layer. A thin film encapsulation layer includes a first encapsulation layer, a second encapsulation layer, and a third encapsulation layer. The first encapsulation layer includes a first inorganic insulating layer including silicon nitride; a second inorganic insulating layer including silicon oxide; and a third inorganic insulating layer including silicon oxynitride. The auxiliary layer has a thickness of 200 Å to 1400 Å, the first inorganic insulating layer has a thickness of 400 Å to 3500 Å, the second inorganic insulating layer has a thickness of 200 Å to 2400 Å, and the third inorganic insulating layer has a thickness of 4000 Å or more.
