ABSTRACT:
A transflective liquid crystal display device has improved light efficiency. A method of fabricating a transflective liquid crystal display device including a thin film transistor substrate having a transmissive region and a reflective region, includes forming a retardation layer on a lower surface of the thin film transistor substrate, aligning a mask having a reflective region pattern on the lower surface of the thin film transistor substrate, and forming a light efficiency enhancer by selectively removing the retardation layer by irradiating a laser onto the lower surface of the thin film transistor substrate through the mask.
