Abstract
In the LCD panel driving circuit, the voltage of first and second buffer amplifiers is supplied to first output pad, the voltage of second and third buffer amplifiers is supplied to second output pad, and voltage of third and fourth buffer amplifiers is supplied to third output pad. Thus, data-line selection switches and output-polarity selection switches are switched in such a way that the voltage supplied to any adjacent output pads is always supplied from adjacent buffer amplifiers.
