摘要: An organic light-emitting element having high efficiency and long lifetime is provided. body provided which includes a host electron-transport property (n-type host), hole-transport (p-type guest such as an iridium complex in the n-type p-type are located so to be adjacent each other. When electron hole injected body, trapped by host. Then, both guest, thus brought into excited state. In this process, less thermal deactivation occurs working rate of high; thus, highly efficient light emission can obtained.
