An object of the invention is to provide an organic light emitting device having a high current density at the time of driving. A means for achieving the object is an organic light emitting device which has an anode and a cathode, has between the anode and the cathode a light emitting layer containing a light emitting organic compound, and has between the anode and the light emitting layer a first functional layer containing a first organic compound, a second functional layer containing a second organic compound and a hole transport layer in this order from the anode side, wherein the first organic compound is an electron accepting organic compound, and the second organic compound is an organic compound having a fused ring or not less than three aromatic rings.
