Abstract
An EL display device includes: a source driver circuit to output a video signal voltage; a gate driver circuit to select a pixel in a display screen; a first capacitor to maintain the video signal voltage; and a drive transistor to supply current to an EL element of a pixel. The video signal voltage is applied to the drive transistor to perform a predetermined operation, and written into the first capacitor. The video signal voltage maintained in the first capacitor is used to perform an offset cancel operation.
