Abstract
A light emitting diode (LED) structure and a LED packaging structure are disclosed. The LED structure includes a sub-mount, a stacked structure, an electrode, an isolation layer and a conductive thin film layer. The sub-mount has a first surface and a second surface opposite the first surface. The stacked structure has a first semiconductor layer, an active layer and a second semiconductor layer that are laminated on the first surface. The electrode is disposed apart from the stacked structure on the first surface. The isolation layer is disposed on the first surface to surround the stacked structure as well as cover the lateral sides of the active layer. The conductive thin film layer connects the electrode to the stacked structure and covers the stacked structure.
