Claim Text:
1. A liquid crystal display device comprising: a liquid crystal display panel configured to include at least one common electrode bar and a plurality of divisional areas perpendicular to the at least one common electrode bar, the plurality of divisional areas including a first divisional area and a second divisional area; a common voltage compensator configured to generate a first compensated common voltage corresponding to the first divisional area, and a second compensated common voltage corresponding to the second divisional area, and apply the first compensated common voltage to the at least one common electrode bar of the liquid crystal display panel when the first divisional area is driven during a first portion of a single frame, and apply the second compensated common voltage to the at least one common electrode bar of the liquid crystal display panel when the second divisional area is driven during a second portion of the single frame, the common voltage compensator comprising: a common voltage controller for generating the common voltage control signal for controlling the common voltage compensator, the common voltage controller comprising: wherein the at least one common electrode bar has a first end electrically connected to an output terminal of the common voltage compensator and a second end electrically connected to an input terminal of the common voltage compensator; and wherein the second compensated common voltage applied during the second portion of the single frame to the second divisional area close to the second end of the at least one common electrode bar is greater than the first compensated common voltage applied during the first portion of the single frame to the first divisional area close to the first end of the at least one common electrode bar.
