Claim:
1. A display device driver for driving a display device in response to a video signal, said display device including a screen containing a plurality of scanning lines and a plurality of data lines that respectively intersect the scanning lines so as to form pixels at the intersection point therebetween, said display device driver comprising: a scanning driver that applies scanning pulses in sequence to respective ones of said plurality of scanning lines; and a data driver that applies pixel drive voltages to the respective ones of said data lines, said pixel drive voltages each varying in correspondence to luminance levels represented by said video signal at the respective pixels, wherein said data driver applies said pixel drive voltages at timings each corresponding to a scan pulse path length of the scanning line that intersects said one of data lines, said scan pulse path length being equal to a length of a distance between an apply point of a scanning pulse and an intersection point where a scanning line intersects said data line.
