Abstract
An organic light emitting diode display is discussed. The organic light emitting diode display can include a first substrate and a second substrate facing the first substrate. The first substrate includes an auxiliary electrode, a bank having an opening exposing at least a portion of the auxiliary electrode, a barrier disposed on the exposed auxiliary electrode, a spacer disposed on the bank and protruding toward the second substrate, a cathode included in an organic light emitting diode and divided by the barrier, one end of the cathode directly contacting the auxiliary electrode, a contact electrode disposed on the cathode and divided by the barrier, one end of the contact electrode directly contacting the auxiliary electrode, and a protective layer interposed between the cathode and the contact electrode. The contact electrode and a power line directly contact each other.
