ABSTRACT:
A transflective LCD panel has a transmissive region and a reflective region and includes a first substrate, a second substrate opposite to the first substrate, a reflective plate formed on the second substrate and located within the reflective region, and a first liquid crystal layer and a second liquid crystal layer that are filled between the first substrate and the second substrate. The first and second liquid crystal layers correspond to the transmissive and reflective regions, respectively. The second liquid crystal layer is doped with a chiral material. When a voltage is applied, liquid crystal molecules in a middle section of the first liquid crystal layer are substantially arranged in a tilt angle θ, and the liquid crystal molecules of the second liquid crystal layer are tilted by the tilt angle and further twisted.
