LIQUID CRYSTAL DISPLAY DEVICE

摘要

This invention relates to a liquid crystal display (LCD) device having the best performance of contrast ratio and color saturation in the transmissive and reflective areas of color LCD by adjusting the thicknesses of two color filters on the lower and upper transparent substrates. The present invention includes a first substrate having a reflective area and a transmissive area, and a plurality of thin film transistors (TFTs) thereon; a dielectric layer on said first substrate; a first color filter on said dielectric layer; an elevated dielectric layer on said first color filter in said reflective area; a first electrode on said elevated dielectric layer in said reflective area and on said first color filter in said transmissive area, wherein the top surface of said first electrode in said reflective area is higher than the top surface of said first electrode in said transmissive area; a liquid crystal layer on said first electrode; a second electrode on said liquid crystal layer; a second color filter on said second electrode; and a second substrate on said second color filter.
