Patent number: 11950497Abstract: A light-emitting element with high emission efficiency and high reliability is provided. The light-emitting element includes a host material and a guest material in a light-emitting layer. The host material has a function of converting triplet excitation energy into light emission and the guest material emits fluorescence. The molecular structure of the guest material is a structure including a luminophore and protecting groups, and five or more protecting groups are included in one molecule of the guest material. The introduction of the protecting groups into the molecule inhibits energy transfer of triplet excitation energy by the Dexter mechanism from the host material to the guest material. As the protecting group, an alkyl group or a branched-chain alkyl group is used.Type: GrantFiled: February 21, 2019Date of Patent: April 2, 2024Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Satoshi Seo, Nobuharu Ohsawa, Takuya Haruyama, Anna Tada
