Patent ID: 7136124

Claim:
A transflective liquid crystal display device comprising: an upper plate having a color filter; a lower plate having a lower electrode layer comprising lower transparent electrodes and reflective electrodes alternately arranged therein; and a liquid crystal layer interposed between the upper plate and the lower plate, wherein the color filter comprises a transparent substrate, a color filter layer covering the transparent substrate, an upper transparent electrode layer covering the color filter layer, and a transparent layer covering the transparent electrode layer, the color filter layer comprises a plurality of color units, each color unit having a first portion and a second portion, the second portion being thicker than the first portion, the first portion of each color unit corresponding to a respective reflective electrode, the second portion of each color unit corresponding to a respective lower transparent electrode, and the transparent layer comprises a plurality of convex protrusions formed on a bottom surface thereof facing the liquid crystal layer, the plurality of convex protrusions corresponding to the reflective electrodes.
