<P>PROBLEM TO BE SOLVED: To suppress a variation in gate potential of a drive transistor. <P>SOLUTION: A transistor Tr1 becomes on state in a reset period, and the drive transistor Tdr is diode connected. Also, a transistor Tr4 becomes on state. At this time, the current flows from the drive transistor Tdr into a feeder 17. Since the feeder 17 is arranged in parallel to a control line, such as a scanning line 121, a light emission period and a reset period change over in a row unit. Accordingly, even if the reset current flows into the feeder 17, the reset current does not influence the gate potential of the drive transistor Tdr during the light emission period. <P>COPYRIGHT: (C)2008,JPO&INPIT |
