ABSTRACT:
An electrically-floating light shielding film is formed on a glass substrate, and a signal line is formed above the light shielding film via a gate insulating film. The light shielding film is formed along the signal line, and has a width larger than that of the signal line. On an interlayer insulating film that covers the signal line, transparent electrodes of neighboring pixels are formed, and a reflective electrode extending from the transparent electrode has a frame portion disposed along the signal line. The reflective electrode is formed the interlayer insulating film. The light shielding film does not overlap the transparent electrode in a plan-view perspective and overlaps the reflective portion in a plan-view perspective. The signal line does not overlap the reflective electrode in a plan-view perspective. Hence, a semitransparent liquid crystal display device that suppresses vertical crosstalk and as well maintains a high aperture ratio is obtained.
