PROBLEM TO BE SOLVED: To provide the driving method of a liquid crystal display device capable of reducing power consumption at the time of the standby state without degrading picture quality of the display device. SOLUTION: In a first frame just after the time when an LCD has recognized the start of a low power consumption mode, in an area where display is needed, a signal VDn and VCOM are supplied respectively to gate lines and common electrodes similarly in a normal mode. Moreover, in an area where display is not needed, the signal VDn and the VCOM are fixed at low levels. As a result, polarities of the signal VDn and the VCOM are not inverted even between adjacent gate lines. In frames from the next frame to (x) number of following frames, in the area where display is needed, the signal VDn and the VCOM are supplied respectively to the gate lines and the common electrodes similarly in the normal mode in each frame. Moreover, in the area where display is not needed, the signal VDn and the VCOM are fixed at low levels and also the outputting of a selection signal to the gate lines is stopped in each frame.
