ABSTRACT:
An IPS mode LCD device and a method for fabricating the same are disclosed. A switching device is formed at each unit pixel and then a passivation layer is formed thereon. A first concave pattern and a second concave pattern at each unit pixel by using one mask are formed, and a common electrode is formed in the first concave pattern and a pixel electrode is formed in the second concave pattern. Accordingly, the entire fabrication process is simplified.
