Abstract
In a pixel memory portion of a display device, as corresponding to each pixel memory unit, there are provided a flip-flop, a voltage selection portion, which selects either white display voltage or black display voltage in accordance with an output signal from the flip-flop, and a liquid crystal capacitance, which reflects the voltage selected by the voltage selection portion in the display state of the pixel that corresponds to the flip-flop. Moreover, the flip-flops respectively included in the pixel memory units within the pixel memory portion are connected in series, forming a shift register.
