Abstract
In an aspect, an organic light emitting diode display including: a substrate; a first electrode and an auxiliary electrode positioned on the substrate and separated from each other; an absorption electrode positioned on the auxiliary electrode; an organic emission layer positioned on the first electrode and having a contact hole exposing the auxiliary electrode and the absorption electrode; and a second electrode positioned on the organic emission layer and connected to the auxiliary electrode and the absorption electrode through the contact hole is provided. In an aspect, the organic light emitting diode (OLED) display may minimize the voltage drop of the driving power passing through the large-sized electrode of the thin film for driving the organic emission layer, and may simplify the removal process of the organic emission layer on the auxiliary electrode by adding the absorption electrode on the auxiliary electrode.
