Decoration member and method for manufacturing same

A decoration member comprising:

• a substrate layer including a plurality of convex or concave structures arranged two-dimensionally such that:
• (i) a first line segment connecting a highest point of any convex structure or a lowest point of any concave structure with a highest point of an adjacent convex structure or a lowest point of an adjacent concave structure, the first line segment defining a first axis direction;
• and
• (ii) a second line segment connecting a highest point of the any convex structure or a lowest point of the any concave structure with a highest point of another adjacent convex structure or a lowest point of another adjacent concave structure, the second line segment defining a second axis direction;
• and
• an inorganic material layer provided on the substrate layer,
• wherein the two-dimensionally-arranged structures are arranged such that the second axis direction forms an angle of greater than or equal to 1 degree and less than or equal to 175 degrees in a clockwise direction with the first axis direction,
• wherein a first cross-section cutting of the plurality of the convex or the concave structures in a first plane (Z1) is a first asymmetric-structured cross-section, and a second cross-section cutting the plurality of the convex or the concave structures in a second plane (Z2) is a second asymmetric-structured cross-section, and wherein the first asymmetric-structured cross-section and the second asymmetric-structured cross-section are the same or different from one another;
• the first plane includes a straight line coinciding with or parallel to the first axis direction, and the second plane includes a straight line coinciding with or parallel to the second axis direction;
• and
• the first plane and the second plane include a straight line passing through a highest point of the convex structures or a lowest point of the concave structures among normal lines on one surface of the substrate layer.
