Abstract
A method of manufacturing an organic light emitting display (OLED) device can include providing an anode electrode and an auxiliary electrode on a substrate; providing a first bank on the auxiliary electrode; providing a second bank between the auxiliary electrode and the anode electrode, in which the second bank is spaced apart from the first bank; providing an organic emitting layer on the anode electrode; and providing a cathode electrode on the organic emitting layer, in which 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.
