Abstract
By a method for producing a liquid crystal cell substrate having a base and a birefringent layer, which includes producing a precursor layer of the birefringent layer by applying a solution of a polymer that hardens to form the birefringent layer, directly onto one surface of the base, and producing the birefringent layer by hardening the precursor layer, the present invention provides a method for producing a birefringent layer on a liquid crystal cell substrate or a liquid crystal cell substrate of a liquid crystal panel used in a liquid crystal display.
