Abstract:
A electroluminescence display device includes a pixel including a selection transistor, a driving transistor, and an EL element, a scanning signal line electrically connected with a gate of the selection transistor, a data signal line electrically connected with a source of the selection transistor, and a carrier injection amount control signal line applying a voltage to the EL element. The EL element includes a first electrode, a third electrode, a first insulating layer between the first electrode and the third electrode, an electron transfer layer between the first insulating layer and the third electrode, a light emitting layer containing an electroluminescence material between the electron transfer layer and the third electrode, and a second electrode located outer to a region where the first electrode, the first insulating layer, the electron transfer layer and the third electrode overlap each other, the second electrode being in contact with the electron transfer layer.
