Abstract
A drive section driving a plurality of pixel circuits by line-sequential scanning is provided. On a plurality of the pixel circuits belonging to one horizontal line, the above-described drive section performs a first preparation drive based on a first voltage in a first preparation period, then performs a second preparation drive based on the first voltage in a second preparation period, and performs writing of luminance information in a subsequent writing period. The second preparation period ends at a timing out of the first preparation periods of other horizontal lines.
