Abstract
A display device includes color display pixels, a driving circuit, and signal lines X, Xand X. The driving circuit is provided with a reference gray scale signal circuit, a digital-to-analog conversion circuit and a signal supply circuit. The signal supply circuits provides signal lines X, Xand Xwith analog signals as video signals when reference gray scale signals are outputted in accordance with color characteristics of the pixels. The signal supply circuit also provides signal lines X, Xand Xwith preliminary analog video signals converted in response to the reference gray scale signals corresponding to color characteristics of other pixels when video signals are supplied to other signal lines during each horizontal scanning period.
