Abstract: The present invention discloses an array substrate for an IPS-LCD device. The IPS-LCD device according to the present invention implements a multi-domain for a liquid crystal layer. The liquid crystal molecules are aligned in various directions with respect to each different domain. Therefore, the different domains compensate for one another such that a color shift is prevented in spite of wide viewing angles. To form the multi-domain, the present invention provides an array substrate having divided common electrode or pixel electrode or both. In another aspect, to form the multi-domain, the present invention provides an array substrate having multi-bar shaped common and pixel electrodes. Each of the common and pixel electrodes has a transverse portion and a perpendicular portion. The transverse portions of the common and pixel electrodes induce a first domain, whereas the perpendicular potions of the common and pixel electrodes induce a second domain.
