Abstract
A liquid crystal display (LCD) and a driving method thereof. The LCD includes: a liquid crystal panel which includes a plurality of pixels formed in intersection areas between a plurality of gate lines and a plurality of data lines, wherein a pair of adjacent pixels share the same data line and are located between a pair of gate lines; a common voltage generator which shifts and outputs a common voltage signal having a polarity, which is reversed one time for a period time and repeated consecutively two time for a ½ period time, for a predetermined time; and a source driver which synchronizes a data signal of a line inversion system with an output timing of the common voltage signal and outputs the data signal to an opposite polarity to a polarity of the common voltage signal to drive the plurality of pixels in a dot inversion system.
