| 摘要 |
An optical element includes a metal layer in which a first direction is a thickness direction; metallic particles provided to be spaced from the metal layer in the first direction; and a light transmitting layer that separates the metal layer from the metallic particles, in which the size T of the metallic particles in the first direction satisfies a relationship of 3 nm≦T≦14 nm, and the size D of the metallic particles in a second direction orthogonal to the first direction satisfies a relationship of 30 nm≦D<50 nm. |
