Transflective liquid crystal display device comprising a patterned spacer wherein the buffer layer and the spacer are a single body and method of fabricating the same

A method of fabricating a color filter substrate for a transflective liquid crystal display device, comprising:

• forming a black matrix on a substrate having a plurality of pixel regions, each of the plurality of pixel regions reflective, transmissive, and black matrix portions;
• forming a buffer layer on the black matrix, the buffer layer having a first open portion corresponding to the transmissive portion of the pixel region and a patterned spacer within the black matrix portion of the pixel region;
• forming a color filter layer on the buffer layer, the color filter layer having a first thickness within the reflective portion of the pixel region and a second thickness within the transmissive portion of the pixel region;
• and
• forming a common electrode on the color filter layer,
• wherein the buffer layer and the patterned spacer are a single body with the patterned spacer protruding from the buffer layer through the color filter layer and the common electrode.
