Retardation substrate, method of manufacturing the same, and liquid crystal display

摘要

A retardation layer that includes regions causing different retardations can be manufactured easily. A retardation substrate includes a substrate and a solidified liquid crystal layer facing its main surface. The solidified liquid crystal layer includes first to third regions, and a degree of depolarization for each of the regions is less than 5.0×10−4. A difference between the maximum and minimum values of the degrees of depolarization obtained for the regions is less than 2.0×10−4.
