Abstract
An organic light emitting diode display is disclosed. The organic light emitting diode display includes a first substrate, a second substrate, and a conductive filler layer between the first substrate and the second substrate. The first substrate includes an auxiliary electrode, a first barrier disposed on the auxiliary electrode, a cathode physically divided by the first barrier and exposing at least a portion of the auxiliary electrode, and a protective layer disposed on the cathode, physically divided by the first barrier, and exposing at least a portion of the auxiliary electrode. The second substrate includes a spacer protruding toward the first substrate and disposed adjacent to the auxiliary electrode and a power line covering at least a portion of the spacer and supplied with a power voltage.
