Transflective liquid crystal display device having reflective electrode with a light-transmitting hole, situated below a transparent electrode

摘要

The present invention discloses a transflective liquid crystal display device, including 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 substrate; a gate electrode arranged on the first transparent substrate; a reflective electrode arranged on the transparent substrate and spaced apart from the gate electrode, 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 electrodes spaced apart from the source electrode, overlapping the second end portion of the semiconductor; 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 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 backlight device supplying light toward the light transmitting hole.
