A light-emitting device includes an anode; a cathode; a first light-emitting unit provided between the anode and the cathode and having at least one light-emitting layer; a second light-emitting unit provided between the cathode and the first light-emitting unit and having at least one light-emitting layer; and a carrier generation layer provided between the first light-emitting unit and the second light-emitting unit, the carrier generation layer generating holes and electrons in response to application of a voltage between the anode and the cathode. The carrier generation layer includes an n-type electron transport layer and an electron-withdrawing layer, the n-type electron transport layer being positioned between_the first light-emitting unit and the electron-withdrawing layer and containing alkali metal oxide and an electron-transporting material having electron transport properties, the electron-withdrawing layer contacting the n-type electron transport layer and containing organic cyanide having an aromatic ring.
