Abstract
The disclosure relates to a light emitting device. The light emitting device includes a first electrode, a first semiconductor layer, an active layer, a second semiconductor layer and a second electrode. The first electrode is electrically connected to the first semiconductor layer. The second electrode is electrically connected to the second semiconductor layer. At least one of the first electrode and the second electrode comprises a metal metamaterial layer. The metal metamaterial layer comprises a number of metamaterial units arranged to form a periodic array. A distance between the metal metamaterial layer and the active layer is less than or equal to 100 nanometers. The display device using the light emitting device is also provided.
