Abstract
A liquid crystal display (LCD) device is disclosed, which obtains a wide viewing angle without gray inversion, stabilizes alignment of liquid crystal layer, and obtains high aperture ratio. The LCD device includes first and second substrates; gate and data lines crossing each other on the first substrate to define a pixel region; a pixel electrode in the pixel region; electric field inducing windows in respective one of two regions of the pixel region; a common auxiliary electrode corresponding to the electric field inducing window of the pixel electrode; a common electrode on the second substrate; a dielectric protrusion on the common electrode corresponding to the periphery of the pixel electrode, and a liquid crystal layer between the first and second substrates.
