Abstract
In the liquid crystal display device adjacent source lines may be short-circuited during horizontal scanning periods. A gate driver sequentially may apply a pixel data write pulse to gate lines in each frame period and may apply a black voltage application pulse during the horizontal scanning periods which is after the lapse of a period of the order of a 2/3 frame from the application of the pixel data write pulse to each gate line. A source driver may connect each source line to a charge sharing voltage fixing power supply during the horizontal scanning periods where the adjacent source lines are short-circuited, and thereby brings a charge sharing voltage to the same value regardless of display gradation.
