Abstract
Transflective liquid crystal displays and fabrication methods thereof. A single gap transflective liquid crystal display includes a first substrate with a reflective region and a transmissive region. A second substrate opposes the first substrate with a gap therebetween. A liquid crystal layer is disposed between the first and second substrates. A color filter is disposed on the first substrate, wherein the color filter is thicker in the transmissive region than in the reflective region, wherein a recess is formed at the reflective region. A first alignment layer is conformably formed on the color filter, forming a second recess in the reflective region. The second recess is filled with a second alignment, wherein the first and second alignment layers provide different orientations and pre-tilt angles for the liquid crystal layer.
