Abstract
A drive device according to the present invention is located in a liquid crystal panel. The drive device is a source driver IC that drives a pixel region of the liquid crystal panel. The drive device includes a comparison circuit and a determination circuit. The comparison circuit detects a potential difference between a potential of a first analog power supply and a potential of a second analog power supply, an analog power supply input from the outside being divided into the first analog power supply and the second analog power supply. The determination circuit determines that it is an abnormal condition when the potential difference detected by the comparison circuit is greater than or equal to a predetermined threshold value.
