摘要：
The present invention provides an organic EL display panel and an organic EL display apparatus that can be driven at a low voltage and that exhibit excellent light-emitting efficiency. Sequentially fixated on a substrate are: a first electrode; auxiliary wiring; a hole injection layer; a functional layer; and a second electrode. The hole injection layer and the second electrode are both formed 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. The hole injection layer contains tungsten oxide and at least 2 nm thick so as to have, in an electronic state thereof, an occupied energy level in a range between 1.8 eV and 3.6 eV lower than a lowest energy level of a valence band in terms of a binding energy.
