Abstract:
A transflective liquid crystal display device, comprising:a first transparent substrate; a second transparent substrate having a color filter and spaced apart from the first transparent substrate; a liquid crystal layer interposed between the first and second transparent substrates; a gate electrode arranged on the first transparent substrate; a reflective electrode arranged on the first transparent substrate and spaced apart from the gate electrode, the gate electrode and the reflective electrode having been formed at the same time, the reflective electrode having a light transmitting hole, the light transmitting hole transmitting light; a first insulating layer arranged on the first transparent substrate while covering the gate electrode and the reflective electrode; a semiconductor layer having first and second ends and being arranged over the gate electrode; a source electrode overlapping the first end portion of the semiconductor layer; a drain electrode spaced apart from the source electrode, overlapping the second end portion of the semiconductor, the drain electrode comprising a metallic material and being formed at an edge of a pixel region defined by a gate line and a data line; a second insulating layer covering the source and drain electrodes and having a first contact hole located on a predetermined portion of the drain electrode; a transparent electrode arranged over the reflective electrode and electrically contacting the drain electrode through the first contact hole and covering a portion of the second insulating layer corresponding to the light transmitting hole, and the first and second insulating layers have a second contact hole on a predetermined portion of the reflective electrode so that the transparent electrode electrically contacts the reflective electrode through the second contact hole; and a backlight device supplying light toward the light transmitting hole.
