A light-emitting element includes a cathode, an anode, a first light-emitting layer disposed between the cathode and the anode, a second light-emitting layer disposed between the first light-emitting layer and the cathode, a third light-emitting layer disposed between the second light-emitting layer and the cathode, a first interlayer disposed between the first and second light-emitting layers that has a function of preventing energy transfer of an exciton between the first and second light-emitting layers, and a second interlayer disposed between the second and third light-emitting layers that has a function of preventing energy transfer of an exciton between the second and third light-emitting layers, wherein the first interlayer has a hole-transporting property higher than that of the second interlayer, and the second interlayer has a electron-transporting property higher than that of the first interlayer.
