Abstract
Disclosed herein is an electroluminescent display device capable of improving reliability of a contact portion between low-potential supply line and a cathode electrode of an organic light emitting diode. The electroluminescent display device includes a low potential voltage supply line disposed on a display panel to supply a low potential voltage to the display panel; a cathode electrode overlapped with the low potential voltage supply line and having at least one contact portion; and an auxiliary cathode electrode overlapped with the low potential voltage supply line and the cathode electrode to connect the low potential voltage supply line to the cathode electrode, wherein a bank layer is disposed between the cathode electrode and the auxiliary cathode electrode to cover a rim of the auxiliary cathode electrode, or the cathode electrode covers a rim of the auxiliary cathode electrode and an inorganic insulation layer.
