PROBLEM TO BE SOLVED: To provide a liquid crystal display device that can prevent continuous application of voltage to pixels when a power source is turned off without causing a significant increase in device cost.SOLUTION: When a liquid crystal display device 100 is turned off, a control circuit (control unit) 2 sets a switching period of a gate bus line to be subjected to writing processing shorter than during image display, and performs power source turn-off processing of applying a predetermined voltage for power source turn-off processing to the respective source bus lines.
