Abstract:
A light-emitting element includes: an anode; a cathode; a light-emitting layer which is provided between the anode and the cathode and emits light as the anode and the cathode are electrically connected to each other; and an organic layer which is provided between the anode and the light-emitting layer to come in contact with both layers. The organic layer has a first function of transporting holes and a second function of preventing electrons infiltrating from the light-emitting layer from staying in the organic layer.
