Abstract
The display device of this invention has a pixel element electrode 80, a plurality of drain signal lines 61 for supplying the digital image signals D0–D2, a plurality of capacitance elements C0–C2 with weighed capacitance value corresponding to the digital image signals D0–D2, a refresh transistor RT for initializing the voltage of the pixel element electrode 80 to the voltage Vsc, and charge transfer transistors TT0–TT2 for supplying the charge accumulated in the capacitance elements C0–C2 to the pixel element electrode 80. An image is displayed by supplying the analog image signal corresponding to the digital image signals D0–D2 to the pixel element electrode 80. The configuration of the peripheral circuits of the pixel element portion is simplified, leading to the reduction of the framing area of the panel.
