A display driver including: a data line driver circuit which drives an output line based on a drive voltage corresponding to display data; a first switching element connected between a first power supply line and the output line; a second switching element connected between a second power supply line and the output line; and a switch control circuit which controls the first and second switching elements. The lengths of first and second periods are determined based on at least part of the display data in a horizontal scanning period which is immediately before a current horizontal scanning period. The first and second switching elements are respectively turned ON and OFF in the first period, and are respectively turned OFF and ON in the second period. After the second period, the first and second switching elements are turned OFF, and the output line is driven by the data line driver circuit.
