Abstract
A liquid crystal laminate includes a substrate including a first diffraction surface and a second base material surface and having optical transparency, a metal layer located on a part of the first diffraction layer, an adhesion layer located on a part of the second base material layer and made of a photocured resin, and liquid crystal layer located on a surface of the adhesion layer at a side opposite to the contact surface of the substrate.
Claims3
A liquid crystal laminate comprising:
- a substrate including a first surface and a second surface, which is opposite to the first surface, and having optical transparency,
- a metal layer on a part of the first surface of the substrate;
- an adhesion layer having a first surface and a second surface, which is opposite to the first surface, the first surface of the adhesion layer is in contact with the second surface of the substrate;
- and
- a liquid crystal layer on the second surface of the adhesion layer, wherein the adhesion layer has a first portion and a second portion, a position of the first portion of the adhesive layer on the second surface of the substrate coincides with a position of the metal layer of the first surface, a position of the second portion of the adhesive layer on the second surface of the substrate coincides with a portion of the first surface of the substrate, which does not have the metal layer, the first portion of the adhesion layer comprises a first photocurable resin and the second portion of the adhesion layer comprises a second photocurable resin, wherein when cured, the first photocurable resin has a first crosslink density and the second photocurable resin has a crosslink density lower than the first crosslink density.
