LIGHT EMITTING DEVICE AND LIGHT EMITTING DEVICE PACKAGE

摘要

A light emitting device includes a first conductive semiconductor layer which is arranged on a substrate, an active layer which is arranged on the first conductive semiconductor layer, a second conductive semiconductor layer which is arranged on the active layer, and a control layer which is arranged under the first conductive semiconductor layer. The control layer includes a plurality of first compound semiconductor layers and a plurality of second compound semiconductor layers. The first compound semiconductor layer or the second compound semiconductor layer has shrinkage stress and includes a dopant.
