ABSTRACT:
Disclosed is a reflective type liquid crystal display device. The liquid crystal display device includes: an upper substrate provided with a polarizing plate on one surface of the upper substrate; a lower substrate spaced away from the other surface of the upper substrate; a liquid crystal layer disposed between the upper and lower substrates; a color filter layer formed at a portion on the other surface of the upper substrate; a self-luminous body coated side by side with the color filter layer in a region besides a pixel region on the other surface of the upper substrate, so as to radiate light by itself depending on the electric current; and a transparent ITO layer covered on the color filter layer and the self-luminous body. It is possible to operate the liquid crystal display device without degradation of reflection efficiency in a dark state wherein light introduced from outside is weak.
