Abstract: A transmissive liquid crystal diffraction element includes a first optically-anisotropic layer and a second optically-anisotropic layer each of which has a liquid crystal alignment pattern in which a direction of an optical axis derived from a liquid crystal compound changes while continuously rotating in at least one in-plane direction, in which a rotation direction of the optical axis in the liquid crystal alignment pattern of the first optically-anisotropic layer and a rotation direction of the optical axis in the liquid crystal alignment pattern of the second optically-anisotropic layer are opposite to each other, and a single period of the liquid crystal alignment pattern in the first optically-anisotropic layer and a single period of the liquid crystal alignment pattern in the second optically-anisotropic layer are the same.

Abstract: A manufacturing method of a laminate includes: providing an optical mask layer on a substrate by printing a first pattern having AM screen tone with a screen ruling of 250 lines or less and having a halftone dotted region having a halftone dot area ratio of 0.5% to less than 99.5% on the substrate using a first ink, and printing a second pattern having a semi-translucent solid region having a print-area ratio of 99.5% or more and a light transmittance of 5% to less than 95% at a position overlapping the halftone dotted region of the first pattern using a second ink; providing a liquid crystal layer containing a liquid crystal compound and a photosensitive chiral agent on a side of the substrate opposite to the optical mask layer; and irradiating the liquid crystal layer with light through the optical mask layer to subject the photosensitive chiral agent to photoreaction.

Abstract: Provided is a display device capable of switching between a wide viewing angle and a narrow viewing angle with a simple configuration and simple control. The problem is solved by providing a display element and an optical switching element which is disposed on a visible side of the display element, in which the optical switching element has a light guiding plate and a light source for causing light to be incident on an end surface of the light guiding plate, and 80% or more of the light emitted from the light guiding plate when the light source is turned on is emitted to a region at an angle of 30° or more with respect to a normal line of the light guiding plate on a surface on the opposite side of the display element.
