Claim 18:
19. The display device of claim 17, wherein
the substrate further includes:
a plurality of signal pads in the pad region and through which the electrical signal is provided to the driving integrated circuit from outside the substrate, and
an edge which is furthest from the display region with the pad region therebetween and extends along a first direction,

the driving integrated circuit further includes:
a plurality of input signal bumps through which the electrical signal is provided to the driving integrated circuit from the plurality of signal pads of the substrate, and
a plurality of output signal bumps through which the electrical signal is provided to the display region of the substrate from the driving integrated circuit,

along the edge of the substrate the plurality of signal pads are adjacent to the plurality of test pads along the first direction, and
within the driving integrated circuit the plurality of output signal bumps are adjacent to the first test bump along the first direction.
