Patent ID: 6912027

Claim:
A transflective liquid crystal display device, comprising: first and second substrates facing into each other, each of the first and second substrates having reflective and transmissive portions; a buffer layer on the first substrate, the buffer layer having a first transmissive hole at the transmissive portion; a color filter layer on the buffer layer and the first substrate, wherein a total thickness of the color filter layer and the buffer layer of the reflective portion is thicker than a thickness of the color filter layer of the transmissive portion; a common electrode on the color filter layer; a pixel electrode at the reflective and transmissive portions; a reflecting layer at the reflective portion, the reflecting layer having a second transmissive hole at the transmissive portion; and a liquid crystal layer between the common electrode and the pixel electrode, wherein the buffer layer at the reflective portion is thicker than a thickness difference between the liquid crystal layer at the transmissive portion and the liquid crystal layer at the reflective portion.
