ABSTRACT:
In a first frame immediately after LCD recognizes a start of a low electric power consumption mode, within a region in which an indication is required, signals VDn and VCOM are supplied to data lines and a common electrode, respectively. In a region in which the indication is not required, the signals VDn and VCOM are fixed to the low level, thus, polarities of the signals VDn and VCOM are not inverted even between gate lines adjacent to each other, in a portion from a next frame to an x-th frame. In each frame, within the region in which the indication is required, VDn and VCOM are supplied to the data lines and the common electrode, respectively. In the region in which the indication is not required, the signals VDn and VCOM are fixed to the low level, in each frame, moreover, an output of a selection signal to the gate line is stopped.
