Abstract
A liquid crystal display device that can reduce picture quality deterioration due to a kickback voltage and can accurately detect a kickback voltage is provided. The liquid crystal display device includes: a liquid crystal panel including a detector configured to generate a kickback voltage detection signal, a detection line for supplying the kickback voltage detection signal, and a ground pattern along and adjacent to one side of the detection line; and a common voltage generator connected to the detection line and configured to generate a common voltage corresponding to the kickback voltage detection signal and to supply the generated common voltage to the liquid crystal panel.
