Reflective liquid crystal display device using a reflective plate having light weight

A reflective liquid crystal display device using a reflective plate having light weight, comprising:

• a transparent insulating substrate;
• a gate bus line and a data bus line formed at an inner side of the substrate and defining a pixel region;
• a pixel electrode formed in the pixel region;
• a switching device operating the pixel electrode by receiving the signals of the gate bus line and the data bus line;
• a black matrix formed on the surface of the substrate and covering a portion at which the gate bus line, the data bus line, and the switching device are formed;
• color filters respectively formed between the black matrixes;
• and
• a plastic reflective plate opposing to the inner side of the substrate, wherein the plastic reflective plate comprises:
• a plastic plate;
• a photoresist layer disposed on the plastic plate and having an uneven portion on the surface thereof;
• a reflective film having a high reflectance coated on the photoresist layer having the uneven portion;
• a planarization layer formed on the photoresist layer so as to planarize the surface of the photoresist layer;
• an alignment layer disposed over the planazation layer;
• and a transparent electrode formed at the back side of the plastic plate.
