摘要 Provided are a light-emitting element in which a driving voltage increase can be suppressed and a light-emitting device which has reduced power consumption by including the light-emitting element. The element includes an EL layer between an anode and a cathode, and has a first, a second, and a third layer between the cathode and the EL layer. The first layer is between and in contact with the cathode and the second layer and includes a hole-transport substance. The second layer is between and in contact with the first the third layers and includes a phthalocyanine-based material. The third layer is between and in contact with the second and EL layers and includes an alkali metal, an alkaline-earth metal, a rare-earth metal, an alkali metal compound, an alkaline-earth metal compound, or a rare-earth metal compound. The phthalocyanine-based material has a metal-oxygen bond.
