A light emitting diode (LED) package includes a substrate, at least one micro LED chip, a black material layer, and a transparent material layer. The substrate has a width ranging from 100 micrometers to 1000 micrometers. The at least one micro LED chip is electrically mounted on a top surface of the substrate and has a width ranging from 1 micrometer to 100 micrometers. The black material layer covers the top surface of the substrate to expose the at least one micro LED chip. The transparent material layer covers the at least one micro LED chip and the black material layer.
