Title:
UNEVEN STRUCTURAL BODY AND LAYERED BODY
Document Type and Number:
WIPO Patent Application WO/2021/085084
Kind Code:
A1
Abstract:
Provided is an uneven structural body with superior designability compared to the prior art. An uneven structural body (20) comprises an uneven layer (22) having, on the surface thereof, a plurality of convex sections or concave sections with a meandering linear shape in plan view. In the uneven layer, the plurality of convex sections or concave sections are formed to be aligned, in plan view, at a pitch of no more than 1000 μm from a first section to an n-th section (n≧10). When an imaginary rectangle of a minimum area circumscribing the entire convex section or concave section is drawn for each concave or convex section and a plurality of pole points where a tangent line is parallel to a linear direction of two mutually opposing sides of the imaginary rectangle are defined as specific pole points (the line terminals are not included in the pole points), and if an operation is repeated to connect, by an x-th imaginary line, one specific pole point of the x-th (1≦x≦n-1) concave or convex section and one specific pole point of the (x+1)-th concave or convex section which is closest to the specific pole point of the x-th concave or convex section, then the linear direction of the x-th imaginary line and the linear direction of the (x+1)-th imaginary line are different.
