Abstract

A light-emitting diode package structure includes a driving substrate, at least one light-emitting unit, and a reflective colloid. The driving substrate has a surface. The light-emitting unit includes at least one mini light-emitting diode and at least one wavelength conversion layer. The mini light-emitting diode is disposed on the surface of the driving substrate and electrically connected to the driving substrate. The wavelength conversion layer covers the mini light-emitting diode. The reflective colloid covers a periphery of the light-emitting unit and the driving substrate. The light-emitting unit is suitable for emitting a light, and the reflective colloid is suitable for reflecting the light so as to focus on a light-emitting direction.
