Electroluminescent display device

A display device, comprising:

• a substrate having a display area and a pad region;
• a thin film transistor disposed on the substrate;
• a first pad and a second pad disposed in the pad region;
• a light-emitting diode disposed in the display area and including a first electrode, a light-emitting layer and a second electrode, the light-emitting diode being electrically connected with the thin film transistor;
• and
• a first auxiliary pad and a second auxiliary pad disposed in the pad region and electrically connected to the first and second pads, respectively,
• wherein the first auxiliary pad includes:
• a first transparent conductive layer, and
• a second metallic layer,
• wherein the second auxiliary pad includes:
• a first transparent conductive layer, and
• a second metallic layer, and
• wherein a surface length between the first auxiliary pad and the second auxiliary pad is greater than a distance between the first auxiliary pad and the second auxiliary pad.
