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, and a conductive filler layer between the first and second substrates. The first substrate includes a bank layer having an opening exposing at least a portion of an anode, a spacer on the bank layer, an organic compound layer and a cathode disposed on the anode, the bank layer, and the spacer, an inorganic layer disposed on the cathode and including a first open hole exposing at least a portion of the cathode on the spacer, and an organic layer disposed on the inorganic layer and including a second open hole exposing at least a portion of the cathode on the spacer. The second substrate includes a power line electrically connected to a portion of the exposed cathode through the conductive filler layer.
