ABSTRACT:
The liquid crystal display device includes pixel electrodes; a common electrode; a plurality of data lines and a plurality of gate lines intersecting each other; a plurality of switchers for the pixel electrodes for supplying signals from the data lines to the pixel electrodes; a gate line driver for scanning the gate lines; a data line driver for driving the data lines in accordance with the gradation to be displayed; and a controller for controlling the gate line driver and the data line driver. The controller includes a signal absence detector for detecting that no signal has been input to the liquid crystal display device. The controller outputs a signal to the gate line driver to make all the gate lines active for a predetermined time after the signal absence detector detects that no signal has been input. The controller outputs a signal to the data line driver to supply an electric potential, applied to the common electrode, to all the data lines for the predetermined time.
