The present invention discloses a reflective plate having lightweight functioning as a substrate and a reflective LCD using the same. The reflective LCD according to the present invention comprises: 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 1s and covering a portion at which the gate bus line, the data bus line, and the switching device are formed; color filters respectively formed at the outsides of the black matrix; 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; a transparent electrode disposed over the planarization layer; and an alignment layer formed over the transparent electrode.

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

Disclosed is a method for forming a reflector of a reflective LCD capable of improving a viewing angle characteristic while simplifying a forming process, the method comprising the steps of: applying a photoresist film on an insulating substrate; dispersing a plurality of spacers over a surface of the photoresist film; curing the photoresist film; rubbing the spacers-dispersed and cured photoresist film, thereby removing the spacers; and performing a vapor deposition of a metal film having a high reflectivity on the photoresist film.
