The invention discloses a liquid crystal display screen, a composite substrate, and a manufacturing method. The composite substrate comprises a substrate, a carbon nano-tube layer, and an optical alignment base material. The carbon nano-tube layer is bonded on the surface of the substrate through the optical alignment base material.
