PROBLEM TO BE SOLVED: To provide a display device which suppresses the generation of d.c. components caused by the signals being inadvertently inputted into data lines and prevents image quality deterioration such as an afterimage and an image sticking, to provide its driving method and an image pickup device having the display device. SOLUTION: In an active matrix type liquid crystal display device, sampling switches..., 18m-1, 18m, 18m+1,... are surely put into an OFF state under the control of a control pulse X during a non-driving period. A complete shut down condition is made between a video signal line 17 and data lines..., 13m-1, 13m, 13m+1,.... A common voltage Vcom given to a common line 15 is supplied to the data lines..., 13m-1, 13m, 13m+1,... through control switches..., 21m-1, 21m, 21m+1,.... Each of potentials of the data lines..., 13m-1, 13m, 13m+1,... is made equal to the potential of opposing electrode of a liquid crystal cell LC.
