Abstract
An embodiment of the present invention provides a liquid crystal display including a liquid crystal panel having a display area and a non-display area; left and right common voltage lines connected to common voltage lines formed in the display area and located in the non-display area on the left and right sides of the display area; and a common voltage compensator that receives feedback common voltages from the left and right common voltage lines and outputs compensated common voltages based on the feedback common voltages, wherein the common voltage compensator divides the display area into a first display area and a second display area with respect to the center of the liquid crystal panel and performs different compensation to the first display area and the second display area.
