An organic light emitting display device can include a substrate; an anode electrode on the substrate; an organic emitting layer on the anode electrode; a cathode electrode on the organic emitting layer; an auxiliary electrode connected with the cathode electrode; a first bank on an upper surface of the auxiliary electrode; and a second bank disposed between the auxiliary electrode and the anode electrode, in which the second bank is formed of a same material as the first bank, and the first and second banks are spaced apart from each other, and a width of an upper surface of the first bank is larger than a width of a lower surface of the first bank, and the cathode electrode is connected with the auxiliary electrode via a gap space between the first bank and the second bank.
