Patent ID: 8829510

Claim:
An organic EL display panel comprising: a substrate; at least one first electrode on or in the substrate; auxiliary wiring on or in the substrate at a distance from the first electrode; a functional layer, including at least a light-emitting layer, above the first electrode; a hole injection layer for injecting holes to the functional layer, the hole injection layer being between the first electrode and the functional layer; and a second electrode above the functional layer, wherein the hole injection layer and the second electrode are both disposed to be continuous above the first electrode and above the auxiliary wiring, the second electrode and the auxiliary wiring are electrically connected by the hole injection layer, and the hole injection layer contains tungsten oxide and has, in an electronic state thereof, an occupied energy level in a range between 1.8 electron volts and 3.6 electron volts lower than a lowest energy level of a valence band of the hole injection layer in terms of a binding energy.
