Light-emitting element, light-emitting device, electronic device, and lighting device

A light-emitting element comprising:

• an EL layer between an anode and a cathode;
• a first layer including a substance having a hole-transport property and an acceptor substance being in contact with the cathode and between the cathode and the EL layer;
• a second layer including a first donor substance and a first substance having an electron-transport property and being in contact with the first layer and between the cathode and the EL layer;
• and
• a third layer including a second donor substance and a second substance having an electron-transport property and being in contact with the second layer and with the EL layer and between the cathode and the EL layer,
• wherein a LUMO level of the first substance having an electron-transport property is lower than a LUMO level of the second substance having an electron-transport property.
