DRIVE DEVICE AND DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a drive device that can achieve desired drive capability in a plurality of output amplifier circuits connected in parallel, and to provide a display device. SOLUTION: The drive device (source driver 1) includes: the plurality of output amplifier circuits 10 connected in parallel; a bias wire (main bias wire 22) for supplying a bias voltage from a bias voltage supply source 25 to the plurality of output amplifier circuits; a power supply wire 31 for supplying power supply voltage from a power supply voltage supply source 35 to the plurality of output amplifier circuits; and a correction unit (buffer 26) for superimposing an offset voltage onto the bias voltage so that a difference between the power supply voltage and the bias voltage supplied to the plurality of output amplifier circuits 10 is to be desirable.
