<P>PROBLEM TO BE SOLVED: To make drive current flow small in a display element. <P>SOLUTION: In a writing period for each pixel PX, a first operation, in which keeping an output control switch SW4 open, a first control terminal of a drive control element DR1, a second control terminal of a drive control element DR2, a first output terminal of the drive control element DR1 and a video signal line DL are connected to each others and a current equivalent to the drive current to be flowed to the display element OLED is flowed to the video signal line DL by setting the potential of a scanning signal line SL1 to a first potential, and a second operation, in which the potential of the scanning signal line SL1 is changed from the first potential to a second potential, in a state of cutting each connection of the first and the second control terminals, the first output terminal and the video signal line DL, are performed sequentially. In an effective display period after the writing period, the drive current is made to flow to the display element OLED, in a state with the output control switch SW4 being closed and each connection of the first and the second control terminals, with the first output terminal and the video signal line DL being cut, the potential of the scanning signal line SL1 is held at the second potential. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
