Abstract: A light emitting diode (LED) package includes a light element, a light transferring layer disposed on the light element, a packaging layer enclosing the light transferring layer, a white wall surrounding the packaging layer and a diffusion film disposed on the packaging layer. The light transferring layer has a light outlet face, a light inlet face opposite to the light outlet face and a peripheral side. The light inlet face faces the light element. The white wall surrounds the peripheral side that is enclosed by the packaging layer.
