Abstract:
A light-emitting package structure includes a light transmissive adhesive layer, a substrate, and at least one light-emitting diode chip. The light transmissive adhesive layer includes a first surface and a second surface facing away from the first surface. The substrate is on the first surface of the light transmissive adhesive layer. The light-emitting diode chip is on the second surface of the light transmissive adhesive layer. The light transmissive adhesive layer has a first portion and a second portion on the second surface, the first portion surrounds the second portion, a vertical projection area of the second portion on the substrate at least entirely covers a vertical projection area of the light-emitting diode chip on the substrate, and a thickness of the second portion is smaller than or equal to a thickness of the first portion.
