Abstract
An in-plane switching liquid crystal display device includes a gate line and a data line on a substrate, the gate and data lines crossing each other to define a pixel region, a thin film transistor electrically connected to the gate and data lines, a pixel electrode connected to the thin film transistor, and a common electrode alternately arranged with the pixel electrode to form n blocks in the pixel region. Widths of some of the blocks are different than widths of other of the blocks.
