Light-emitting element, display device, and electronic appliance

An electronic device comprising:

• a light-emitting device comprising:
• a substrate comprising an organic compound;
• a semiconductor layer over the substrate;
• a gate electrode adjacent to the semiconductor layer with an insulating layer interposed between the gate electrode and the semiconductor layer;
• an anode over the substrate, the anode electrically connected to the semiconductor layer;
• a first layer over the anode, the first layer generating holes;
• a light emitting layer comprising a light emitting material over the first layer;
• a second layer over the light emitting layer, the second layer generating electrons;
• a third layer comprising metal oxide over the second layer, the third layer generating holes;
• and
• a cathode being in contact with the third layer.
