摘要:A light emitting device is provided. The light emitting device comprises an activelayer comprising a plurality of well layers and a plurality of barrier layers. The bather
layers comprise a first barrier layer having a first band gap which is the nearest to thesecond conductive type semiconductor layer, a second barrier layer adjacent to the firstbarrier, and a third barrier layer between the second bather layer and the first conductivetype semiconductor layer. The well layers comprise a first well layer having a third bandgap different from the first band gap between the first and second bather layers, and asecond well layer between the second barrier layer and the third barrier layer, thesecond well layer having a second band gap. The first well layer has a thickness thinnerthan that of the second well layer.
