摘要:
A display device of at least one embodiment of the present invention has a connection changeover circuit, including switch elements for time-division driving, formed on a liquid crystal panel, and the switch elements are paired so that two switch elements in each pair are connected in parallel to one video signal line. The paired switch elements are turned on at the same time, and immediately before one of the switch elements is turned off upon completion of a charging period for its corresponding video signal line, only the other switch element is turned off. As a result, while maintaining drive performance, it is possible to solve the impact of fieldthrough phenomenon caused by one of the switch elements, which are transistors, and also reduce parasitic capacitance formed in the other switch element, thereby suppress the impact of fieldthrough phenomenon caused by that switch element.
