Abstract

The present invention provides a birefringent lens material for a stereoscopic image display, the birefringent lens material containing two or more liquid crystal compounds each having at least one polymerizable functional group, a birefringent lens for a stereoscopic image display, the birefringent lens being formed by using the lens material, and a method for producing a birefringent lens for a stereoscopic image display using the lens material. The birefringent lens material for a stereoscopic image display and the birefringent lens for a stereoscopic image display of the present invention are good in terms of optical characteristics, durability, and productivity, in particular, productivity. The method for producing a birefringent lens for a stereoscopic image display of the present invention has good productivity.
