Abstract
A light emitting element is disclosed, including a substrate layer, a first metal layer and a second metal layer stacked sequentially on the substrate layer, and an organic material layer disposed between the first metal layer and the second metal layer. The first metal layer includes a first metal portion and a second metal portion that cover a surface of the substrate layer, and an opening portion disposed between the first metal portion and the second metal portion and exposes a portion of the surface. The organic material layer emits light having a wavelength within a first range. A first coupling generated between the first metal portion and the second metal layer shifts the light from the first range to a second range. A second coupling generated between the second metal portion and the second metal layer shifts the light from the first range to a third range.
