Abstract
A control circuit can prevent malfunction of a scan line driving circuit even when any inputted signal is not in normal timing relation due to any cause. The control circuit includes: a counterfor counting up to a predetermined count number based on a clock inputted; a comparator arranged at the subsequent stage of the counter to determine whether or not the counter is under counting; and a protection circuit arranged at subsequent stage of the comparatorfor normalizing a start pulse that starts operation of the scan line driving circuit, even when any input signal of a timing controller is abnormal, by outputting a normalized start pulsevia AND gateto which a start pulsegenerated by the timing controller and an output signalof the comparatorare inputted.
