Abstract:
The organic EL display panel includes: an active matrix substrate including a thin-film transistor; and an organic EL element disposed on the active matrix substrate, the organic EL element including, in the order from the active matrix substrate side, a cathode electrically connected to the thin-film transistor, a first charge conversion layer in contact with the cathode, a first hole injection layer, a first hole transport layer, a first light-emitting layer, a first electron transport layer, a first electron injection layer, a second charge conversion layer, and an anode in contact with the second charge conversion layer, the first charge conversion layer designed to inject electrons into the cathode and emit holes to the first light-emitting layer side, the second charge conversion layer designed to inject holes into the anode and emit electrons to the first light-emitting layer side.
