Decoration member and decoration member manufacturing method

A decorative member comprising:

• a base;
• a pattern layer provided on the base;
• and
• inorganic layers comprising a first light absorption layer, a light reflection layer, and a second light absorption layer sequentially provided on the pattern layer, thereby defining a first interface between the first light absorption layer and the light reflection layer, and a second interface between the second light absorption layer and the light reflection layer,
• wherein each of the first light absorption layer and the second light absorption layer independently is a single-layered structure comprising one material or two or more materials selected from a group consisting of:
• indium (In), silicon (Si), tantalum (Ta),
• wherein the pattern layer comprises a convex portion or a concave portion shape having a cross section with an asymmetric structure,
• wherein the pattern layer comprises thermosetting resin or ultraviolet curable resin,
• wherein ΔE12 indicated in the following Equation 1 is 1 or more, and
• wherein in Equation 1, L1*, a1*, and b1* are coordinate values of CIE lightness (L1*) and chromaticity (a1*, b1*) of the first light absorption layer, and L2*, a2* and b2* are coordinate values of CIE lightness (L2*) and chromaticity (a2*, b2*) of the second light absorption layer,
