An organic electroluminescent element having high light emission efficiency, high color purity, and a long light emission lifetime, and a display device using the same are provided. In an organic electroluminescent element 11 having red light emission characteristics in which an organic layer 14 including a light emitting layer 14c is held between an anode 13 and a cathode 15, the light emitting layer 14c contains a guest material having the red light emission characteristics and a host material of a polycyclic aromatic hydrocarbon compound with a mother skeleton having 4 to 7 ring members. An electron transport layer 14d containing a specific benzimidazole derivative is provided adjacent to the light emitting layer 14c.
