A common line is eliminated, and one terminal of the capacitor, which has been heretofore connected to the common line, is connected to the scan line of another display cell adjacent to the display cell having the capacitor. A scan line driving circuit supplies to respective scan lines a stepped pulse formed of a voltage V1 and a voltage V2 sufficiently larger than the voltage V1. A data line driving circuit supplies to the respective data lines a voltage not smaller than the voltage V1 and not larger than a voltage V3 (but smaller than the voltage V2) as a data voltage.
