For an image display apparatus, cost reduction is enabled to prevent display errors while ensuring operational margin to prevent display errors even when the delay time of gate line driving signals is large. A source driver of a liquid-crystal display apparatus includes a data latch circuit for supplying display data to a decode circuit. A gate line inactivation transition detecting circuit detects inactivation of each of a plurality of gate lines and activates a detect signal for a certain period with that timing. The data latch circuit updates the held display data in response to activation of the detect signal.
