Abstract
The present specification relates to a decorative member comprising a base and inorganic layers comprising a first light absorption layer, a light reflection layer, and a second light absorption layer sequentially provided on the base, in which ΔE12 indicated in Equation 1 is 1 or more, and a method of manufacturing the decorative member.
Claims15
A decorative member comprising:
- a base;
- and
- inorganic layers comprising a first light absorption layer, a light reflection layer, and a second light absorption layer sequentially provided on the base,
- wherein ΔE12 indicated in the following Equation 1 is 1 or more, and
- ΔE12=√{square root over ((L1*−L2*)2+(a1*−a2*)2+(b1*−b2*)2)} [Equation 1]
- 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.
