Abstract
A package structure is provided. The package structure has a light-emitting region and a non-light-emitting region that is adjacent to the light-emitting region, and includes a substrate, a first light-emitting layer, a second light-emitting layer and a third light-emitting layer. The first light-emitting layer, the second light-emitting layer and the third light-emitting layer are sequentially stacked on the substrate. Each of the first light-emitting layer, the second light-emitting layer and the third light-emitting layer includes a transparent adhesive layer disposed in the light-emitting region, a light-emitting diode (LED) chip disposed on the transparent adhesive layer, a redistribution layer formed on the LED chip and extending from the light-emitting region to the non-light-emitting region, and a planarization layer disposed on the LED chip and the redistribution layer.
