Abstract

There is provided a method for producing a birefringent lens for a stereoscopic image display using a birefringent material having two or more liquid crystal compounds each having at least one polymerizable functional group. The method includes the steps of providing the birefringent lens material; applying the birefringent lens material onto an alignment layer that has been subjected to an alignment treatment in a uniaxial direction, and forming the coating film into a lens shape by conducting curing with ultraviolet light.
