Capacitive light-emitting element display device and driving method therefor

A capacitive light-emitting element display device comprising:

• a plurality of capacitive light-emitting elements arranged at a plurality of intersections of drive lines and scanning lines and connected between said scanning lines and said drive lines;
• scanning switch means for connecting said scanning lines to either first or second potential, said first and second potentials being different from each other;
• drive switch means for connecting said drive lines to a higher potential of said first and second potentials or a drive source;
• light emission control means for controlling said drive switch means and said scanning means, said light emission control means, operative in synchronism with a scanning period in which said scanning switch means connects selected one of said scanning lines to the higher potential of said first and second potentials, for controlling said drive switch means to selectively connect said drive lines to said drive source to force selected capacitive light-emitting elements to emit light, and simultaneously controlling said scanning switch means to connect said scanning lines, not selected, to a lower potential of said first and second potentials;
• and
• adjusting means for adjusting the higher potential of said first and second potentials.
