Abstract
A multi-domain liquid crystal display device includes first and second substrates facing each other; a plurality of gate bus lines arranged in a first direction on the first substrate and a plurality of data bus lines arranged in a second direction on the first substrate to define a plurality of pixel region; a thin film transistor at a crossing area of the gate and data bus lines; a common-auxiliary electrode at outside and inside of the pixel region; a pixel electrode in the each pixel region, the pixel electrode connecting the thin film transistor; at least one series of windows inducing electric field in a plurality of specified directions in the pixel electrode; an alignment layer on at least one substrate between the first and second substrates; and a liquid crystal layer between the first and second substrates.

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.
