Abstract
A light emitting display device having a plurality of light emitting elements connected to intersecting points of a plurality of anode lines and cathode lines arranged in a matrix. Either one of the anode lines and the cathode lines are used as scanning lines, and the others are used as driving lines. While one of the scanning lines is scanned during a scanning period, a driving source is synchronously connected to one of the driving lines so that a light emitting element connected to an intersecting point of the one scanning line and the one driving line is caused to emit light. Immediately after the scanning period of the one scanning line is started, a first driving source is connected to the one driving line, and subsequently, in exchange for the first driving source, a second driving source is connected to the one driving line.
