Abstract
A package structure for a light emitting diode (LED) includes a substrate structure and a reflective layer. The substrate structure sequentially includes a conduction board, an insulation layer, and a conductive layer. The substrate structure has an opening to expose the conduction board. The reflective layer configured to support and electrically couple to a first electrode of the LED is disposed in the opening. The reflective layer is electrically coupled to the conduction board and electrically insulated from at least a portion of the conductivity layer, which is coupled to a second electrode of the LED.
