A source driver generates a plurality of gradation voltages on the basis of gradation reference voltages (VH255-VL255) which are generated with a gradation reference voltage generation circuit, and drives data lines using the generated gradation stepped voltages. A control unit sets a standby interval (Tw) prior to cutting off the source driver power source, and controls the gradation reference voltage generation circuit such that all of the gradation reference voltages (VH255-VL255) reach the same voltage (VQ) in the standby interval (Tw). Thus, the same voltage is written to a pixel circuit, a charge which remains in the pixel circuit is discharged, and an afterimage, burn-in, and flicker, which are caused by a remaining charge when the power source is cut off, are avoided. |
