A liquid crystal display includes a voltage providing unit for providing a common voltage which is a direct-current (DC) voltage level in each of a plurality of first periods of time, in each of a plurality of second periods of time, and in each of a plurality of third periods of time, wherein each first period of time is separated from each second period of time by at least one third period of time, wherein the DC voltage levels in at least one first period of time, at least one second period of time, and at least one third period of time are different from each other.
