Patent number: 12295256Abstract: A light-emitting element having a long lifetime is provided. A light-emitting element exhibiting high emission efficiency in a high luminance region is provided. A light-emitting element includes a light-emitting layer between a pair of electrodes. The light-emitting layer contains a first organic compound, a second organic compound, and a phosphorescent compound. The first organic compound is represented by a general formula (G0). The molecular weight of the first organic compound is greater than or equal to 500 and less than or equal to 2000. The second organic compound is a compound having an electron-transport property. In the general formula (G0), Ar1 and Ar2 each independently represent a fluorenyl group, a spirofluorenyl group, or a biphenyl group, and Ar3 represents a substituent including a carbazole skeleton.Type: GrantFiled: October 4, 2023Date of Patent: May 6, 2025Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Takao Hamada, Hiromi Seo, Kanta Abe, Kyoko Takeda, Satoshi Seo
