ABSTRACT:
The object of the invention is to obtain a high contrast ratio and a better aperture ratio. The invention relates to a reflective liquid crystal display device comprises: a liquid crystal layer (3); a front base layer (5) and a rear base layer (1) which are located on both main surface sides of the liquid crystal layer; a transparent common electrode (4) supported by the front base layer (5); and a composite layer (2) supported by the rear base layer (1), which has a function of reflecting external light from a side of the front base layer (5) and a function of driving pixels, the composite layer (2) including electrically conductive bus-lines (22′) which are arranged in matrix and are able to apply voltages for driving the pixels. The device is characterized in that the bus-lines (22′) are formed from a material having a substantially low optical reflectivity.
