A display panel drive suppresses dither patterns in a displayed image. Each of the display lines of the panel is divided into M display line groups including a group of [M≅(k-1)+1]th display lines (where M is a natural number, and k is a natural number of n/M or smaller), a group of [M≅(k-1)+2]th display lines, . . . and a group of [M≅(k-1)+M]th display lines. A different offset value is added to pixel data corresponding to each display line group to derive multi-grayscale pixel data. Then, a lighting or extinction mode setting is done based on the pixel data with respect to each pixel cell belonging to the display line groups, each different in at least M subsubfields among subfields constituting a video signal field. In one example, the luminance levels represented by the pixel cells vertically adjacent to one another in a screen are varied.
