    摘要: An organic light-emitting element includes an anode, a functional layer, and a hole injection layer between the anode and the functional layer. The functional layer contains an organic material. The hole injection layer injects holes to the functional layer. The hole injection layer comprises tungsten oxide and includes an occupied energy level that is approximately 1.8 electron volts to approximately 3.6 electron volts lower than a lowest energy level of a valence band of the hole injection layer in terms of binding energy.
