The present invention relates to a light emitting element and a display device including the same, which may present a high-efficiency characteristic. The light emitting element according to one embodiment of the present invention comprises: a first electrode; a hole transporting area which is disposed on the first electrode; a light emitting layer which is disposed on the hole transporting area; an electron transporting area which is disposed on the light emitting layer; and a second electrode which is disposed on the electron transporting area. The hole transporting area comprises: a first hole transporting layer which is disposed adjacent to the first electrode and includes a first amine compound represented by formula 1 below; and a second hole transporting layer which is disposed between the first hole transporting layer and the light emitting layer and has a refraction index greater than that of the first hole transporting layer. The conductivity of the first hole transporting layer is between 6.0 x 10^-5 cm / V / s and 10.0 x 10^-4 cm / V / s.
