A liquid crystal display includes a liquid crystal panel that displays an image signal, a backlight unit supplying light to the liquid crystal panel, and a backlight control circuit to scan the backlight unit. The backlight control circuit supplies a pulse width modulation signal to rows of the backlight unit, which are adjacent to rows being scanned, such that the rows adjacent to the rows being scanned have a brightness lower than a brightness of the rows being scanned.

An apparatus for providing grayscale voltages and a display device using the same are provided. The display device includes a grayscale voltage provider that provides grayscale voltages using a first reference voltage and a second reference voltage in accordance with a selection signal. A data driver applies data voltages to data lines using the grayscale voltages and an image signal. A gate driver successively provides a gate-on voltage to the gate lines. A display panel displays an image for each frame using the data voltages and the gate-on voltage.
