摘要 |
An organic EL element includes a hole injection layer that yields excellent hole conduction efficiency. The organic EL element includes an anode, a cathode, and functional layers that include organic material between the anode the cathode. The functional layers include a hole injection layer that injects holes into the functional layers. The hole injection layer is a metal oxide film that includes a metal oxide. The metal atoms constituting the metal oxide include both metal atoms at a maximum valence thereof and metal atoms at a valence less than the maximum valence, and the metal oxide film includes metal oxide crystals having a particle diameter on the order of nanometers.
