A driving chip of a display device is provided to reduce the resistance differences between wirings by controlling the resistance level of connecting wirings of a plurality of output part, thereby preventing signal delay or signal distortion. A plurality of driver circuits(311) produces the driving signal. A plurality of output pads(312) outputs the driving signal to the external signal line. A plurality of connection wirings(313) connects a plurality of driver circuits and plurality of output pads. The driving chip having resistance control mean controls the resistance of each connection wirings among a plurality of connection wirings in one at least.
