ABSTRACT:
A LCD panel includes a plurality of pixel elements. Each pixel element includes a first substrate, a second substrate and an optical filter portion. The first substrate and the second substrate are parallel to each other, and a liquid crystal layer is sealed between the first substrate and the second substrate. The first substrate includes a reflective portion, and the second substrate includes a color filter layer. The color filter layer disposed between the first substrate and the second substrate has an opening opposite to the reflective portion. The optical filter portion is disposed in the opening of the color filter layer for providing color compensation in a reflection mode.
