Abstract
A retardation film made of a polymerized liquid crystal material of the present invention includes: a first region having a first flat surface pattern; and a second region having a second flat surface pattern, wherein a thickness in the first region is different from that in the second region, thereby retardations in the first region and in the second region are different from each other.
