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.
