Reflective liquid crystal display device

A reflective liquid crystal display device comprising:

• a liquid crystal layer;
• a front base layer and a back base layer which are located on both main surface sides of the liquid crystal layer;
• a transparent common electrode supported by the front base layer;
• and
• a composite layer supported by the back base layer, which has a function of reflecting external light from a side of the front base layer and a function of driving pixels,
• the composite layer including electrically conductive bus-lines which are arranged in matrix and are able to apply voltages for driving the pixels, and including an insulating layer covering the bus-lines and pixel electrodes for applying a voltage to the liquid crystal layer for each pixel in accordance with signals supplied to the bus-lines,
• wherein the insulating layer is formed from a material which does not substantially have optical direct-reflecting property but substantially has optical non-transmissivity, and
• wherein the pixel electrodes each extend across an entire width of one of the bus-lines via the insulating layer.
