    Abstract: A novel light-emitting element or a highly reliable light-emitting element is provided. The light-emitting element includes an anode, a cathode, and an EL layer between the anode and the cathode. The EL layer includes at least a light-emitting layer. The light-emitting layer includes at least a first organic compound and a second organic compound. The energy for liberating halogen from a halogen-substituted product of the first organic compound in a radical anion state and in a triplet excited state is less than or equal to 1.00 eV. The amount of halogen-substituted product in the second organic compound is not increased with an increase in driving time of the light-emitting element.

    Abstract: Provided is a light-emitting element which has an anode, a light-emitting layer over the anode, an electron-transport layer over and in contact with the light-emitting layer, an electron-injection layer over and in contact with the electron-transport layer, and a cathode over and in contact with the electron-injection layer. The light-emitting layer has an electron-transport property, and the electron-transport layer includes an anthracene derivative. The light-emitting layer further includes a phosphorescent substance. This device structure allows the formation of a highly efficient blue-emissive light-emitting element even though the phosphorescent substance has higher triplet energy than the anthracene derivative which directly contacts with the light-emitting layer.
