Light-emitting device having package structure with quantum dot material and manufacturing method thereof

Abstract

A light-emitting device includes a light-emitting unit, a light-transmitting layer, a wavelength conversion structure, and a reflective layer. The light-emitting unit includes a top surface and a first side surface. The light-transmitting layer covers the top surface and the first side surface of the light-emitting unit. The wavelength conversion structure is located on the light-transmitting layer. The wavelength conversion structure includes a wavelength conversion layer, a first barrier layer located on the wavelength conversion layer, a second barrier layer located under the wavelength conversion layer, and a third barrier layer covering side surfaces of the wavelength conversion layer, the first barrier layer, and the second barrier layer. The reflective layer surrounds the light-transmitting layer and the wavelength conversion structure.
