Abstract
Provided is a display device containing quantum dots. A display device includes a display area. The display area has a light emitting device in which a first electrode, a layer between the first electrode and an emitting layer, the emitting layer, a layer between the emitting layer and a second electrode, and the second electrode are stacked in this order on a substrate. The emitting layer is formed of an inorganic layer containing quantum dots, and the light emitting device is a top emission device. A thin film transistor connected to the light emitting device is preferably an n-ch TFT.
