Patent number: 11963430Abstract: An object is to provide a highly reliable display unit having a function of sensing light. The display unit includes a light-receiving device and a light-emitting device. The light-receiving device includes an active layer between a pair of electrodes. The light-emitting device includes a hole-injection layer, a light-emitting layer, and an electron-transport layer between a pair of electrodes. The light-receiving device and the light-emitting device share one of the electrodes, and may further share another common layer between the pair of electrodes. The hole-injection layer is in contact with an anode and contains a first compound and a second compound. The electron-transport property of the electron-transport layer is low; hence, the light-emitting layer is less likely to have excess electrons. Here, the first compound is the material having a property of accepting electrons from the second compound.Type: GrantFiled: April 14, 2023Date of Patent: April 16, 2024Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Taisuke Kamada, Ryo Hatsumi, Daisuke Kubota, Naoaki Hashimoto, Tsunenori Suzuki, Harue Osaka, Satoshi Seo

Patent number: 11930703Abstract: A novel organic compound is provided. An organic compound that emits light with high chromaticity is provided. An organic compound that emits blue light with high chromaticity is provided. An organic compound with high emission efficiency is provided. An organic compound having an excellent hole-transport property is provided. An organic compound having high reliability is provided. An organic compound that has a naphtho[2,3-b;7,6-b?]bisbenzofuran skeleton or a naphtho[2,3-b;7,6-b?]bisbenzothiophene skeleton and has a molecular weight of less than or equal to 5000 is provided. The present inventors have found that the organic compound is a significantly effective skeleton as a luminophor of a light-emitting element. The organic compound has high emission efficiency and exhibits favorable blue light emission; thus, a light-emitting element using the organic compound can be a blue light-emitting element with high emission efficiency.Type: GrantFiled: March 8, 2018Date of Patent: March 12, 2024Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Kyoko Takeda, Harue Osaka, Satoshi Seo, Tsunenori Suzuki, Naoaki Hashimoto, Yusuke Takita
