Patent ID: 8253902

Claim:
A liquid crystal display device comprising: a first substrate, wherein a pixel region is defined by a gate line and a data line, an auxiliary electrode is formed in the same layer as the gate line and parallel to the gate line, an electric field guide window is formed parallel to the auxiliary electrode within the pixel region, a pixel electrode that is divided into two or more sub-pixel electrodes by the electric field guide window, and a first alignment layer includes more than two domains, a first and a second of which are aligned in opposite alignment directions; a second substrate facing the first substrate, wherein a dielectric rib is formed in a diagonal within the pixel region, and a second alignment layer includes more than two domains including third and fourth domains aligned in opposite alignment directions; and a liquid crystal layer interposed between the first and the second substrates, wherein when the first substrate and the second substrate are attached, the first to fourth domains are aligned to first to fourth alignment directions different from one another within the pixel region, and wherein the dielectric rib is disposed on a flat portion of the sub-pixel electrode parallel to the first substrate.
