Abstract
An optical element includes a metal layer having a thickness in a first direction; metallic particles spaced apart from the metal layer in the first direction; and a light transmitting layer separating the metal layer from the metallic particles. The metallic particles are disposed in a lattice shape in a second direction orthogonal to the first direction and in a third direction orthogonal to the first direction and the second direction. A distance between adjacent metal particles in the second and third directions is S, and 6 nm<S<40 nm.
