Electroluminescent display device

An electroluminescent display device, comprising:

• a lower substrate divided into an active area and a non-active area;
• a thin film transistor disposed above the lower substrate;
• a planarization layer disposed above the thin film transistor;
• a light emitting diode disposed above the planarization layer, and including an anode, a light emitting unit, and a cathode;
• a bank disposed on the planarization layer to partition an emission area;
• an upper substrate disposed opposite to the lower substrate;
• a filler filled in a space between the upper substrate and the light emitting diode;
• a dam structure enclosing the filler in the non-active area;
• a plurality of alignment holes disposed between the active area and the dam structure, and provided by removing a portion of the bank;
• and
• a plurality of guide pins provided on the upper substrate of the non-active area to be fitted into the plurality of alignment holes,
• wherein the plurality of guide pins are in contact with the filler, and
• wherein the plurality of guide pins are disposed within the filler.
