Abstract
Transflective liquid crystal display devices and fabrication methods thereof. A single cell gap transflective liquid crystal display device includes a first substrate with a reflective region and a transmissive region. A second substrate opposes the first substrate. A liquid crystal layer is disposed between the first and second substrates. A reflective structure is disposed on the first substrate, thereby forming a recess at the transmissive region. A first alignment layer is conformably formed on the first substrate covering the reflective structure, thereby forming a second recess at 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.
