ABSTRACT:
A liquid crystal display device and a method of fabricating the same are disclosed. The device, as disclosed, reduces the number of masks required to fabricate. Thus, cost is reduced and yield is increased. The device includes a plurality of gate lines, a plurality of data lines crossing the gate lines such that active regions are defined near the crossover points, thin film transistors are formed near the active regions, and a plurality of pixel electrodes are formed within regions defined by the adjacent gate and data lines. Also, pixel electrodes overlap gate lines and the two electrodes function as a storage capacitor. A fabrication method includes forming a gate line; forming a data line region, protections layers, and an active area where drain and source electrodes are spaced apart a predetermined distance; forming a data line, a gate line protection layer, and a gate insulating layer; and forming pixel electrodes by depositing a transparent conductive material, such that each pixel electrode also overlaps a portion of a gate line.
