Abstract: A light emitting display device may include a circuit layer having an auxiliary power electrode disposed on a substrate, a protective layer covering the circuit layer, a contact portion exposing a portion of the auxiliary power electrode, and an undercut structure disposed on a portion of the auxiliary power electrode and configured to include an undercut region. The undercut region may be formed at at least a portion of the periphery of the undercut structure.
