Abstract
A light emitting device includes an electrode layer, a first metal layer, an organic material layer and a second metal layer stacked sequentially. The first metal layer includes a first metal portion and a second metal portion separated from the first metal portion at a first lateral distance, and the first metal portion and the second metal portion have a first period. The organic material layer includes a first emitting region separating the first metal portion and the second metal portion. The first lateral distance and the first period enable a lateral plasma coupling generated between the first metal portion and the second metal portion, such that light generated by the organic material layer at the first emitting region has a gain in a first waveband, or a peak wavelength of the light generated by the first emitting region shifts to the first waveband.
