Patent ID: 7133004

Claim:
A flat display device comprising: a plurality of pixels arranged substantially in a matrix; a plurality of thin-film transistors that are provided to drive the respective pixels; a plurality of gate electrodes that are disposed to extend in a horizontal direction, spaced from each other at predetermined intervals, and connected to gate terminals of the thin-film transistors; a plurality of source electrodes that are disposed to extend in a vertical direction, spaced from each other at predetermined intervals, and connected to source terminals of the thin-film transistors; a plurality of storage capacitance elements that are connected to drain terminals of the thin-film transistors and to the pixels; a plurality of first storage capacitance electrodes that are disposed to extend in the horizontal direction, spaced from each other at predetermined intervals, and connected to one part of the pixels via the storage capacitance elements; and a plurality of second storage capacitance electrodes that are disposed to extend in the horizontal direction, spaced from each other at predetermined intervals, and connected to the other part of the pixels via the storage capacitance elements; wherein a first compensation voltage applied to each of the first storage capacitance electrodes has a voltage polarity different from that of a second compensation voltage applied to each of the second storage capacitance electrodes, and a video signal voltage applied via the source electrode to the source terminal of the thin-film transistor which is included in the thin-film transistors connected to the same gate electrode and is connected to the first storage capacitance electrode via the storage capacitance element has a voltage polarity different from that of a video signal voltage applied via the source electrode to the source terminal of the thin-film transistor which is connected to the second storage capacitance electrode via the storage capacitance element.
