摘要

A viewing surface of a reflection layer has a plurality of first reflection surfaces, a plurality of second reflection surfaces, and a third reflection surface. The distance between the first reflection surfaces and the third reflection surface in the thickness direction of a substrate is a distance that allows the observation surface of the reflection layer to be interposed by an interference between a light reflected from the first reflection surfaces and a light reflected from the third reflection surface To give off light of a first color. The distance between the second reflection surfaces and the third reflection surface in the direction of the thickness of the substrate is a distance that enables the observation surface of the reflection layer by interference between a light reflected from the second reflection surfaces and a light reflected from the third reflection surface To give off light of a second color different from the first color. The viewing surface of the reflective layer emits a third color light having the first color light and the second color light.
