A liquid crystal display screen includes a first substrate, a first alignment layer, a liquid crystal layer, a second alignment layer, and a second substrate. The first substrate is opposite to the second substrate. The liquid crystal layer is sandwiched between the first substrate and the second substrate. The first alignment layer and the second alignment layer are respectively disposed on the first substrate and the second substrate facing the liquid crystal layer. The first alignment layer and the second alignment layer respectively include a plurality of parallel first grooves and second grooves. An alignment direction of the first grooves is perpendicular to that of the second grooves. Furthermore, at least one of the alignment layers includes a carbon nanotube layer and a fixing layer. The fixing layer is disposed on the carbon nanotube layer, and facing the liquid crystal layer.
