PROBLEM TO BE SOLVED: To provide a drive unit of a display device, even when wiring lengths of a plurality of wires for connecting a display device and a driver are different, capable of displaying images without any display unevenness.SOLUTION: A display device and a source driver are connected by a plurality of external wires. A bias voltage generation section generates a bias voltage for controlling internal operation current of a plurality of amplifiers in the source driver and supplies it to the respective amplifiers via a bias voltage supply line. A bias voltage supply line is wired so as to shorten the wiring length from the bias voltage generation part, such that, as an amplifier is connected to a longer-length external wire, the bias voltage to be supplied to the amplifier is made high. |
