Abstract
An organic light emitting display apparatus includes a substrate; an anode electrode on the substrate; an auxiliary electrode on the substrate; an organic emission layer on the anode electrode; a cathode electrode on the organic emission layer and on the auxiliary electrode; an insulating bank on the auxiliary electrode, the bank overlapping a first portion of the auxiliary electrode and exposing a second portion of the auxiliary electrode; a first partition wall on the auxiliary electrode; a second partition wall on the first partition wall and covering the exposed second portion of the auxiliary electrode in plan view. A separation space is between the second partition wall and the bank, the cathode electrode is electrically connected to the auxiliary electrode through the separation space between the second partition wall and the bank, and the second partition wall is supported by the first partition wall and the bank.
