PROBLEM TO BE SOLVED: To provide a highly durable organic light emitting device having a light output with high efficiency and high luminance. SOLUTION: The molecule has at least one partial structure containing an indole ring which may have a substituent, and at least one partial structure containing a carbazole ring which may have a substituent. An organic compound having a long phosphorescence lifetime, which is typified by an organic compound, is used for the organic light-emitting element. [Selection] Figure 1 |
