Abstract: An organic light emitting diode display has uniform light emission efficiency over the entire pixel area. The organic light emitting diode display comprises: a substrate having a red pixel area, a green pixel area, and a blue pixel area arrayed in a matrix; an anode electrode in the red, green, and blue pixel areas; a hole injection layer including an organic material with an extinction coefficient less than about 0.13 and on the anode electrode covering a whole surface of the substrate; an emission layer on the hole injection layer; an electron injection layer on a whole surface of the emission layer; and a cathode electrode on a whole surface of the electron injection layer.

Abstract: An organic light emitting display device is discussed. The organic light emitting display device in one embodiment includes at least one light emitting layer between an anode and a cathode, and an electron transport layer between the at least one light emitting layer and the cathode. The electron transport layer may include a first electron transport material for blocking holes from the light emitting layer to the electron transport layer, and a second electron transport material for assisting in a transfer of electrons to the light emitting layer, wherein the first electron transport material and the second electron transport material have different triplet exciton energy levels and different electron mobilities.
