Abstract

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 opposite to the first 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, and face the liquid crystal layer. The first alignment layer and the second alignment layer respectively include a plurality of parallel first grooves and second grooves perpendicular to the first grooves formed thereon facing the liquid crystal layer. Furthermore, at least one of the alignment layers includes a carbon nanotube layer and a fixing layer disposed thereon facing the liquid crystal layer. The carbon nanotube layer includes at least one carbon nanotube film pulled out from an array of carbon nanotubes.

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...
