Abstract
Provided is a drive circuit that includes a gradation voltage generation unit that generates a plurality of gradation voltages that can be supplied to a signal line. The drive circuit further includes a voltage selector that selects, from among the plurality of gradation voltages, whether to supply a gradation voltage of the same voltage level as an assumed gradation voltage to a signal line or to supply a gradation voltage close to the assumed gradation voltage to a signal line.
