Abstract
A plurality of pixel electrodes, TFTs to control the switching of the pixel electrodes, scan lines to supply scan lines to the gates of the TFTs, and data lines to supply image signals to the pixel electrodes via the TFTs when the TFTs are put into an ON state are provided on a substrate. A scan-signal supply circuit to line-sequentially supply the scan signals is further provided. The scan-signal supply circuit holds the scan signals to an intermediate potential for a predetermined period in the middle of changing the potential of the scan signals between a high potential that puts the TFTs into the ON state and a low potential that puts the TFTs into the OFF state.
