Liquid crystal display screen

Abstract

The invention relates to a liquid crystal display screen, which comprises a first substrate, a second substrate, a liquid crystal layer, a first alignment layer and a second alignment layer, wherein the first substrate and the second substrate are arranged oppositely; the liquid crystal layer is arranged between the first substrate and the second substrate; the first alignment layer and the second alignment layer are respectively arranged on the surfaces of the first substrate and the second substrate close to the liquid crystal layer; the surfaces of the first alignment layer and the second alignment layer close to the liquid crystal layer are correspondingly provided with a plurality of first grooves and a plurality of second grooves respectively; and the arrangement direction of the first grooves is vertical to the arrangement direction of the second grooves. At least one alignment layer of the liquid crystal display screen comprises a carbon nano tube layer and a fixing layer, wherein the carbon nano tube layer comprises at least one carbon nano tube film which is obtained by directly drawing from a carbon nano tube array; and the fixing layer is arranged on the surface of the carbon nano tube layer close to the liquid crystal layer.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a liquid crystal display using carbon nanotubes as an alignment layer. Background technique [0002] Liquid crystal alignment technology is one of the key technologies to determine the quality of liquid crystal display, because the quality of liquid crystal alignment technology will directly affect the quality of the final liquid crystal display. A high-quality liquid crystal display requires a stable and uniform initial alignment of the liquid crystal, and the thin layer that induces the alignment of the liquid crystal is called the liquid crystal alignment layer. [0003] Currently known alignment layer materials used for liquid crystal displays include polystyrene and its derivatives, polyimide, polyvinyl alcohol, polyester, epoxy resin, polyurethane, polysilane, etc., the most common is polyamide imine. These materials are subjected to film friction method, obliquely evaporated S...
