ABSTRACT:
A liquid crystal display device includes an array substrate having reflective and transmissive regions in a pixel region, wherein the array substrate includes a reflective electrode corresponding to the reflective region and a pixel electrode on a first substrate. A color filter substrate defines the reflective region and the transmissive region in the pixel region. The color filter substrate includes a color filter with first and second portions that correspond to the respective transmissive and reflective regions on a second substrate. The thickness of the second portion is less than a thickness of the first portion. The combined thickness of the scatter and the thickness of the second portion is greater than the thickness of the first portion; and a liquid crystal layer between the array and color filter substrates.
