Abstract
The disclosure relates to a light emitting device. The light emitting device includes an insulative transparent substrate, a light emitting material layer, and a metal metamaterial layer. The metal metamaterial layer is located between the insulative transparent substrate and the light emitting material layer. The metal metamaterial layer includes a number of periodically aligned metamaterial units. Because the plasmon of the metamaterial can control electromagnetic properties in nanoscale, light from the light emitting device can be polarized in nanoscale. Thus, the light emitting device can emit polarized light. The display device using the light emitting device is also provided.
