摘要： The present invention aims to provide an optical element for displaying colors of high chroma level, with a structure that reduces data generation load and with little observation-angle-dependent chromatic change, and an article equipped with the optical element. The optical element of the present invention includes: a concavo-convex structure forming layer that has a concavo-convex structure on one surface; and a light-reflecting layer that covers at least part of a surface of the concavo-convex structure of the concavo-convex structure forming layer. In the optical element, the concavo-convex structure forming layer includes a unit group made up of a plurality of units whose concavo-convex structures are different from each other; each of the units has a flat portion and either a plurality of convexities or a plurality of concavities, with an upper surface of each convexity or a bottom surface of each concavity being substantially parallel to a surface of the flat portion; the convexities or the concavities adjacent to each other have center-to-center distances that are not constant; the convexities or the concavities have a constant height or depth; and in the unit group, units having an identical concavo-convex structure are not arrayed at a pitch of less than 150 µm.

摘要： A close-contact multi-layer type diffractive optical element having a homogeneous low-refractive-index and high-dispersion resin layer is produced with satisfactory workability. Among two optical members constituting a diffractive plane, a low-refractive-index and high-dispersion member is formed, using a resin precursor composition containing bifunctional fluorine-containing (meth)acrylate and bifunctional (meth)acrylate having a fluorene structure.

摘要： A curved surface diffraction grating fabrication method for fabricating a curved surface diffraction grating having a desired curvature with high accuracy, includes: a step of forming a diffraction grating pattern on a flat-shaped silicon substrate; a step of curving the silicon substrate on which the diffraction grating pattern is formed, by pressing, in a heated state, a fixing substrate having a shape with a desired curved surface onto the silicon substrate and of fixing the silicon substrate on which the diffraction grating pattern is formed to the fixing substrate having the shape with the curved surface, to fabricate a curved surface diffraction grating cast; and a step of bringing a member having flexibility into contact with the curved surface diffraction grating cast, to transfer the diffraction grating pattern to the member.
