Abstract
A liquid crystal display device includes a liquid crystal display panel having a plurality of pixels; a detector included in an interior of the liquid crystal display panel for detecting a variance of a kickback voltage; and a compensation common voltage generator reflects the variance of the kickback voltage detected by the detector and controls a common voltage to be supplied to the liquid crystal display panel. The detector includes at least one or more detection pixels, and the detection pixels are electrically connected to a gate line arranged in the liquid crystal display panel and to a detection line which is arranged neighboring to the data line disposed close to the edge of the liquid crystal display panel.
