ABSTRACT:
A transflective liquid crystal display device includes a thin film transistor disposed at a corner of a pixel region, the thin film transistor including a gate electrode, a semiconductor layer, a source electrode, and a drain electrode, a reflector disposed in the pixel region and spaced apart from the thin film transistor, the reflector formed of the same material as one of the gate, source, and drain electrodes, a color filter disposed within the pixel region, the color filter having one of red, green, and blue colors, a black matrix over the thin film transistor along color filter borders of adjacent pixel regions, and a pixel electrode formed of a transparent conductive material adjacent to the color filter, the pixel electrode having a first end portion contacting the drain electrode of the thin film transistor, wherein the pixel region is divided into a reflective portion including the reflector and a transmissive portion absent of the reflector.
