More Information
Summary:The present invention relates to an organic light emitting element. The organic light emitting element comprises: a first electrode; a second electrode facing the first electrode; a light emitting layer interposed between the first electrode and the second electrode; a hole transport region interposed between the first electrode and the light emitting layer; and an electron transport region interposed between the light emitting layer and the second electrode. Therefore, the organic light emitting element has a low driving voltage, high efficiency and a long lifespan, and increases low-voltage efficiency. 유기 발광 소자가 개시된다.
