Abstract:
An organic light emitting display device including a plurality of pixels having a first sub-pixel and a second sub-pixel comprises a base substrate; a first anode disposed on the base substrate in the first sub-pixel; a second anode disposed on the base substrate in the second sub-pixel; an anode connection part connected to the first and second anodes; a driving transistor including a drain electrode that contacts the anode connection part and switching a driving power supplied to the first and second anodes; an organic light emitting layer disposed on the first and second anodes; a cathode disposed on the organic light emitting layer; and a dummy repair part including a plurality of metal layers overlapping each other with an insulating film interposed therebetween in a laser irradiation area, wherein at least one metal layer among the plurality of metal layers contacts the drain electrode and the cathode has an opened shape in the laser irradiation area.
