PURPOSE: To perform pseudo impulse displays for reducing afterimages when performing a moving picture display in an active matrix type display device without increasing the frequency of a driving signal and changing the mechanism of a back light. CONSTITUTION: The displaying of pictures is performed by forming liquid crystal capacitors 4 in vicinities of intersection parts of signal lines 2X and scanning lines 2Y. An auxiliary capacitor 5 for holding a potential difference when performing a display is provided with respect to the liquid crystal capacitance 4. One of auxiliary capacitance electrodes 8 in both electrodes of the capacitor 5 is connected to a switching element 3 together with a pixel electrode 7 being one side in both electrodes of the capacitance 4. After the element 3 is brought into conduction selectively with the scanning line 2Y and capacitance 4 and the capacitor 5 are charged with a video signal from the signal line 2X, after a fixed time is elapsed, a signal which changes in a direction along which luminance of a display by the capacitor 4 is lowered is applied to the electrode of other side of capacitor 5 by an auxiliary capacitance driver 9 and, then, a pseudo impulse display is performed. Thus, the afterimage characteristic of the display device is improved.
