A liquid crystal display includes a first base plate, a second base plate, a first alignment film, a second alignment film and a liquid crystal layer. The first base plate and the second base plate separately have an inner surface and the second base plate is located with its inner surface opposite to the inner surface of the first base plate. The first alignment film is arranged on the inner surface of the first base plate and comprises a plurality of juxtaposed one-dimensional nanostructures oriented in a first direction. Wherein the one-dimensional nanostructures cooperatively function as at least one of a first polarizer and a first transparent electrode. The second alignment film is arranged on the inner surface of the second base plate, and the liquid crystal layer is sandwiched between the first alignment film and the second alignment film.
