A decorative member comprising:
- a color developing layer including a light reflective layer and a light absorbing layer provided on the light reflective layer;
- and
- a substrate provided on one surface of the color developing layer;
- wherein the color developing layer or the substrate includes a pattern layer;
- wherein the pattern layer includes a convex portion or concave portion shape having an asymmetric-structured cross-section,
- wherein the convex portion or concave portion includes a first inclined surface and second inclined surface,
- wherein an angle of the first inclined surface and the second inclined surface is 80 degrees to 100 degrees,
- wherein a difference between an inclined angle of the first inclined surface and the second inclined surface is 30 degrees to 70 degrees,
- wherein the light absorbing layer includes a copper oxide (CuaOx);
- and
- ω of the light absorbing layer, represented by the following Equation 1, is greater than or equal to 0.001 and less than or equal to 0.6 when conducting a component analysis on any one point of the light absorbing layer:
