Abstract
A liquid crystal display includes a first insulation substrate, gate lines disposed on the first insulation substrate and extending in a first direction, storage electrode lines disposed on the first insulation substrate and extending in the first direction, data lines extending in a second direction substantially perpendicular to the first direction and intersecting the gate lines and the storage electrode lines and, thin film transistors disposed in pixel areas, pixel electrodes disposed in the pixel areas and connected to the thin film transistors, ripple detecting wiring disposed proximate to a first gate line of the gate lines, a connection line which transmits a ripple signal from the ripple detecting wiring, a ripple detector connected to the connection line, and a ripple compensator which generates a compensation voltage based on the ripple signal received from the ripple detector and applies the compensation voltage to the storage electrode line.
