Light emitting element

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 organic material layer emits light having a wavelength within a first range, and a coupling generated between the first metal portion and the second metal layer shifts the peak wavelength of the light from the first range to a second range.
