<p>A circuit for driving an active matrix type of liquid crystal display apparatus comprises a scan signal line driving circuit; a source driver (52) that outputs a video signal the polarity of which is frame-inverted, while being inverted in synchronism with the horizontal scan intervals; a reference voltage producing part (70) that is coupled to the source driver (52); and an auxiliary capacitive electrode driving circuit that outputs, to an auxiliary capacitive power supply line, an auxiliary capacitive power supply line voltage the polarity of which is inverted each frame. The reference voltage producing part (70), which includes selecting circuits (86) each of which selects either a reference power supply voltage during a normal display or a reference power supply voltage at a display commencement, supplies the reference power supply voltage at the display commencement as a reference power supply voltage for the source driver (52) during the first frame interval just after the display commencement, thereby suppressing the occurrence of horizontal thread-like emission lines during the first frame interval just after the display commencement.</p> |
