Claim 0:
1. A display device comprising:
a substrate including:
a display region including a display structure which displays an image, and
a pad region through which an electrical signal is provided to the display region;

a driving integrated circuit which contacts the substrate at the pad region thereof and includes:
a plurality of test bumps which receive test signals from outside the driving integrated circuit, the plurality of test bumps including a first test bump, a second test bump and a third test bump,
a first region including both the first test bump and the second test bump,
a second region including the third test bump and spaced apart from the first region, and
a circuit wire commonly connected to each of the first test bump, the second test bump and the third test bump;

a plurality of test pads in the pad region and through which the test signals are provided to the driving integrated circuit from outside the substrate, the plurality of test pads including first to tenth test pads spaced apart from the driving integrated circuit and arranged along a first direction; and
a plurality of connection wires in the pad region and through which the test signals are provided to the plurality of test bumps from the plurality of test pads, the plurality of connection wires including:
a first connection wire which connects the first test pad to the first test bump of the driving integrated circuit;
second and third connection wires which connect the second and third test pads, respectively, to the second test bump of the driving integrated circuit; and
fourth and fifth connection wires which connect the fourth and fifth test pads, respectively, to the third test bump of the driving integrated circuit.
