An electroluminescent display device includes a substrate, a first electrode on the substrate, a connection pattern on the substrate and formed of a same material as the first electrode, a bank covering edges of the first electrode and the connection pattern, a light-emitting layer on the first electrode, a second electrode on the light-emitting layer, the bank, and the connection pattern, and an auxiliary pattern between the second electrode and the connection pattern, wherein a side surface of the auxiliary pattern has a greater inclination angle than a side surface of the bank.
