Abstract: An organic light emitting diode display is disclosed. The organic light emitting diode display includes a first substrate and a second substrate facing each other. The first substrate includes an anode included in an organic light emitting diode, an auxiliary electrode, a barrier on the auxiliary electrode, a bank layer including a first opening exposing at least a portion of the anode and a second opening simultaneously exposing at least a portion of the auxiliary electrode and at least a portion of the barrier, a cathode included in the organic light emitting diode and divided by the barrier, a contact electrode disposed on the cathode and divided by the barrier, and a protective layer interposed between the cathode and the contact electrode. The contact electrode and the power line directly contact each other.
