PROBLEM TO BE SOLVED: To improve display quality by preventing an after image phenomenon at the time of interrupting display in an active matrix type display device. SOLUTION: Before interrupting display, all the pixel electrodes are supplied with display signals before interrupting, and charges held by auxiliary capacitance 9 are discharged before halting the display. Since this operation eliminates the afterimage, the display can clearly be changed over when halting the display from normal operation, and display quality is improved.
