<P>PROBLEM TO BE SOLVED: To surely correct variation in the threshold voltage of a drive transistor even when discharging a voltage between the terminals of held capacity in a plurality of periods via a drive transistor and correcting the variation in threshold voltage of the drive transistor, by applying an active matrix type image display device using an organic EL element, for example. <P>SOLUTION: A scanning line for outputting a drive signal DS for a power source is set to a floating status in the entire period or some period of the pauses T1, T2 of a threshold voltage correcting process. <P>COPYRIGHT: (C)2010,JPO&INPIT |
