Abstract

An organic light emitting display device may include a first auxiliary electrode, a first first-group first-color corresponding electrode, a second first-group first-color corresponding electrode, and a first group electrode. The second first-group first-color corresponding electrode is larger than the first first-group first-color corresponding electrode. The first group electrode overlaps both the first first-group first-color corresponding electrode and the second first-group first-color corresponding electrode. A first portion of the first group electrode directly contacts the first auxiliary electrode and is positioned closer to the first first-group first-color corresponding electrode than to the second first-group first-color corresponding electrode.
