    摘要： To provide a light-emitting element with high emission efficiency or long lifetime, in which the use amount of a phosphorescent compound is small. To provide a light-emitting element including a light-emitting layer between a pair of electrodes, wherein the light-emitting layer includes a phosphorescent compound, a first organic compound, and a second organic compound, and the combination of the first organic compound and the second organic compound forms an exciplex. The light-emitting element transfers energy by utilizing the overlap between the emission spectrum of the exciplex and the absorption spectrum of the phosphorescent compound and thus has high energy transfer efficiency, even when the concentration of the phosphorescent compound is low.

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