ABSTRACT:
An in-plane switching (IPS) type LCD and method for fabricating the same that solves problems of aperture loss and luminance reduction resulting from a bonding margin of upper and lower substrates, and securing a picture quality by relative increase of the storage capacitance Cst. The in-plane switching (IPS) type LCD including gate lines on a lower substrate in a first direction, data lines on opposite side of a unit region of two sub-pixel regions and perpendicular to the gate lines respectively, a common line spaced apart and parallel to the gate lines, a plurality of common electrodes in the unit region, thin film transistors at cross points of the gate lines and the data lines, a protection film on an entire surface of the lower substrate, the protection film having a contact hole to expose a drain electrode of each of the thin film transistors, pixel electrodes alternately arranged between the common electrodes, each pixel electrode connected to the drain electrode through the contact hole, and a storage electrode on the protection film over the common line.
