Abstract
(EN)
The present invention addresses the problem of providing a novel optical element which can be used for various purposes. The problem is solved by the optical element having a liquid crystal layer in which the alignment of a liquid crystal compound is fixed, and which has a film thickness distribution of 1.1< (in-plane maximum value /in-plane minimum value) <100.
