An active matrix electroluminescent (OEL) display device including a p-type organic thin-film transistor (TFT) is provided. This device has a high aperture ratio, and is easily produced in an array structure. The display device includes a counter electrode, an intermediate layer including at least a light emitting layer on the counter electrode, a pixel electrode formed on the intermediate layer, a first electrode that is disposed on the pixel electrode and insulated from the pixel electrode, a second electrode that is disposed on the pixel electrode and connected to the pixel electrode, a p-type organic semiconductor layer contacting the first electrode and the first drain electrode, and a first gate electrode that is disposed on the p-type organic semiconductor layer and insulated from the first electrode, the first drain electrode, and the p-type organic semiconductor layer.
