A single gap transflective liquid crystal display driven by fringe electric field in the transmissive (T) region and vertical electric field in the reflective (R) region was designed with formation of high pretilt angle larger than 45°through polymerization of an UV curable reactive mesogen monomer at the surface in the R region, the effective cell retardation value becomes half of that in the T region where the LCs are homogenously aligned. Consequently, a transflective display driven by a vertical and fringe electric field with a single cell gap and single gamma curves is realized.
