LIQUID CRYSTAL LENS

摘要

A liquid crystal lens of this invention is provided with (i) a first substrate having (a) a first electrode that has a hole and (b) a second electrode that is within the hole of the first electrode, and spaced from the first electrode; (ii) a second substrate having a third electrode; and (iii) a liquid crystal layer that is formed between an electrode formation surface of the first substrate and an electrode formation surface of the second substrate. In this liquid crystal lens, a functional film is arranged between the second substrate and the liquid crystal layer. At least part of the functional film has a region that has a continuous composition gradient in a film thickness direction.
