<p>A signal-line driving circuit configured to supply a signal voltage having the positive or negative polarity to each of signal lines connected to display cells (of, e.g. a liquid crystal display), arranged to form a matrix. Each cell is subjected to a polarity inversion driving operation according to inversion of the polarity of the signal voltage. The signal-line driving circuit includes an output buffer section, wherein the output buffer section employs a positive-polarity operating amplifier, a negative-polarity operating amplifier, a first output buffer, a second output buffer, and a switch group.</p> |
