Inorganic EL elements, display elements, image display devices, and systems

摘要

PROBLEM TO BE SOLVED: To provide a DC drive type inorganic EL element which emits light with a sufficiently low voltage and high efficiency. .. An inorganic EL element 350 in which an anode 314, a hole transport layer 346, a light emitting layer 344, an electron transport layer 342, and a cathode 312 are laminated, and the hole transport layer 346 is an oxide. An inorganic EL element 350 which is a film, the light emitting layer 344 is an oxide film, and the electron transport layer 342 is an oxide film. [Selection diagram] Fig. 1
