ABSTRACT:
A liquid crystal display device having a wide viewing angle and a high aperture ratio. The present invention includes first and second substrates, gate and data lines on the first substrate to define at least one pixel region, a thin film transistor formed at a crossing between the gate and data lines. A pixel electrode is connected to the thin film transistor in the pixel region, the pixel electrode having a first electric field inducing window. An auxiliary electrode is at a position corresponding to the first electric field inducing window. A black matrix layer is on the second substrate. A color filter layer is on the black matrix layer. A common electrode is on the color filter layer, the common electrode having a second electric field inducing window or dielectric protrusion at a position corresponding to an end portion of the pixel electrode. A liquid crystal layer is between the first and second substrates.
