Patent ID: 7098973

Claim:
A transflective liquid crystal display device comprising: an upper plate having a color filter, a half wave plate and an upper polarizer; a lower plate having a transparent substrate, an insulating layer formed on a top surface of the transparent substrate, a lower electrode layer comprising lower transparent electrodes and reflective electrodes alternately formed on the insulating layer, and a lower polarizer formed on a bottom surface of the transparent substrate; 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, and a transparent layer covering the color filter layer and comprising a plurality of convex protrusions formed on one or more bottom surfaces thereof, and the color filter layer further comprises a plurality of black matrix units and 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; wherein the transparent layer serves to fill gaps between the color units and the upper transparent electrode of the upper substrate; wherein the transparent layer further comprises a plurality of convex protrusions formed on bottom surfaces thereof.
