A color display of high numerical aperture and multiple gray scales, which can realize multicoloring and area gray scales is accomplished by simplifying the pixel circuit constitution of the display device. A pair of transistors which hold video signals by bridging alternating power supply sources are used as an output circuit to a pixel electrode, and a capacitance is connected to the pixel electrode, whereby the data writing state is controlled by making use of a charge stored in the capacitance.
