Abstract
An organic light emitting diode display is disclosed. The organic light emitting diode display includes a first substrate including an organic light emitting diode, a second substrate including a power line supplied with a power voltage and facing the first substrate, and a conductive filler layer between the first substrate and the second substrate. The first substrate includes an auxiliary electrode, a first barrier on the auxiliary electrode, a cathode physically divided by the first barrier and exposing at least a portion of the auxiliary electrode, a contact electrode disposed on the cathode, physically divided by the first barrier, and exposing at least a portion of the auxiliary electrode, and a protective layer between the cathode and the contact electrode. One end of the cathode directly contacts the auxiliary electrode, and one end of the contact electrode directly contacts the auxiliary electrode.
