Anisotropic film containing a copolymer including a monomer containing a dichroic dye and liquid crystal display containing the antisotropic film

A method for producing an anisotropic film which comprises forming a copolymer of a monomer containing a dichroic dye having a carbon-carbon unsaturated bond with a different monomer having a carbon-carbon unsaturated bond to obtain a film, wherein the dichroic dye having a carbon-carbon unsaturated bond is oriented in the film,

• wherein the film is formed by coating, on a substrate having been subjected to orientation, a solution containing the monomer containing a dichroic dye having a carbon-carbon unsaturated bond, the different monomer having a carbon-carbon unsaturated bond and a polymerization initiator, orienting the dichroic dye contained in the solution, and performing a copolymerization reaction in the oriented state.
