A liquid crystal display (200) includes a first base plate (202), a second base plate (220), a liquid crystal layer (238) located between the first base plate and the second base plate, and two alignment films (210, 228). The two alignment films are respectively positioned on inner surfaces of the first base plate and the second base plate. Each alignment film is a film of oriented carbon nanotubes (212, 230). An oriented direction of the carbon nanotubes on the first base plate is perpendicular to that of the carbon nanotubes on the second base plate. A manufacturing method for the liquid crystal display is also disclosed.
