Abstract

The present invention relates to a liquid crystal display which comprises a first base and a second base, which are arranged oppositely; a liquid crystal layer is arranged between the first base and the second base; a first alignment layer is arranged on the surface of the first base which is close to the liquid crystal layer and the surface of the first alignment layer which is close to the liquid crystal layer has a plurality of paralleled first grooves; a second alignment layer is arranged on the surface of the second base which is close to the liquid crystal layer and the surface of the second alignment layer which is close to the liquid crystal layer has a plurality of paralleled second grooves; and the orientation of the first grooves of the first alignment layer is perpendicular tothat of the second grooves of the second alignment layer. Wherein, at least one alignment layer inside the liquid crystal display comprises a carbon nano tube layer which consists of at least one carbon nano tube film comprising a plurality of carbon nano tubes of end to end connection and directional arrangement.

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 the friction method, obliquely evaporated Si...
