Document Type and Number:

WIPO Patent Application WO/2019/142903

Kind Code:

A1

Abstract:

The present invention provides a three-dimensional object that varies the way light appears and provides a more excellent design. A decoration member (10) that is a three-dimensional object includes a sheet (31), a lens unit (32), and an image formation unit (33). The sheet (31) is light transmissive and has a first sheet surface (31a) that is curved. The lens unit (32) is curved along the first sheet surface (31a). The lens unit (32) is provided with a plurality of protruding lenses (23) arranged in parallel. The image formation unit (33) is provided with an image (37) having a principal axis direction (ML). An angle (θ) made between the principal axis direction (ML) and the longitudinally extending direction (ED) of a lens (23) satisfies 0° ≤ θ ≤ 40° or 50° ≤ θ ≤ 90°. The above-described curved surface has a first region (AR1) through a third region (AR3) each having different normal directions. The curved surface is configured so that one of the normal directions in each region is inclined relative to a planar surface including the other two normal directions.
