ABSTRACT:
A source driver outputs a data signal and a reset (black) signal alternately to a source line. Four-hundred and eighty gate lines are divided into three groups each comprising 160 lines, and connected to gate drivers. A display control section outputs a discriminant signal, a scan start signal and a clock signal to the gate drivers, where the nth gate line is selected with the data signal outputted by the source driver, and where the (n+160)th gate line is selected with the reset signal outputted. Further, n is shifted sequentially. By writing the reset signal during the latter ⅓ of one frame like this, light leakage of pixels that are changed over from white display to black display is eliminated. Also, blurs of edge portions of a motion picture are reduced. Thus, display grade for motion pictures is enhanced with a minimum improvement.
