Abstract

A light-emitting diode package structure including a chip carrier portion, a light-emitting diode chip, and a package material is provided. The light-emitting diode chip is disposed on the chip carrier portion of the package. The package material is filled in the chip carrier portion and covers the light-emitting diode chip. The package material includes a matrix material, a plurality of first powder particles, and a plurality of second powder particles. The first powder particles and the second powder particles are distributed in the matrix material. Each first powder particle is a wavelength conversion material. Each second powder particle has a shell-like structure.
