| 发明名称 | Organic EL element, organic EL panel having organic EL element, organic EL light-emitting apparatus, and organic EL display apparatus | ||
| 摘要 | An organic EL element includes: an anode; a cathode; a buffer layer; and a hole injection layer between the anode and the buffer layer, the hole injection layer including a nickel oxide including both nickel atoms with a valence of three and nickel atoms with a valence of two. In the hole injection layer, a ratio of the number of nickel atoms with a valence of three to the number of nickel atoms with a valence of two, expressed in percentage, is equal to or greater than 60%. | ||
