Title: OPTICAL ELEMENT AND METHOD FOR PRODUCING SAME
Abstract:
The present invention provides an element obtained by controlling liquid crystal alignment to achieve alignment of a discretionary state in a discretionary location in a liquid crystal element, and more specifically provides an optical element and/or a method for producing the element. The present invention provides the optical element, which has I) a first transparent base material layer, II) a first aligned liquid crystal alignment film layer, III) a liquid crystal layer filled with a photoreactive liquid crystal composition, and IV) a second transparent substrate layer in that order, wherein the photoreactive liquid crystal composition in layer III) contains: (A) a photoreactive polymer liquid crystal having a photoreactive side chain that brings about at least one type of reaction selected from the group consisting of (A-1) photocrosslinking and (A-2) photoisomerization; and (B) a low molecular weight liquid crystal.
