Abstract
A display device driver that can display images while preventing noise and suppressing display unevenness is provided. When pixel drive voltages corresponding to the luminance levels of respective pixels indicated by a video signal are applied to the data lines of the display device, the pixel drive voltages are applied to data lines that intersect the scanning lines of the display device at positions where the delay time is larger, at timing later than timing of applying the pixel drive voltages to the data lines that intersect the scanning lines at positions where the delay time is smaller, the delay time being a period of time between start of application of the scanning pulse by the scanning driver and actual arrival of the scanning pulse.
