Abstract
A driving circuit includes a plurality of output terminals to be electrically connected to scan wirings, respectively, a scan controlling unit for selecting one or plural output terminals to output a driving signal for the scan wiring from among the plurality of output terminals, and a potential correcting unit for controlling a potential of the driving signal on the basis of a difference voltage between the potential of the selected output terminal and a reference potential. In addition, a reference potential adjusting unit adjusts the reference potential in response to a current passing through the selected output terminal in order to correct a voltage drop caused by a member connected to the selected output terminal. The reference potential adjusting unit changes adjustment of the reference potential in response to the number of the selected output terminals and turns off adjustment of the reference potential in the case that the number of the selected output terminals is more than 1.
