1. A pixel package, comprising:
a carrier, having a top surface and an upper conductive layer formed on the top surface;
a first light-emitting unit, arranged on the upper conductive layer and having a first light-emitting surface and a first side surface;
a second light-emitting unit, arranged on the upper conductive layer and having a second light-emitting surface and a second side surface;
a reflective layer, arranged on the top surface and connected to the conductive layer; and
a light-absorbing layer, arranged on the reflective layer and connected to the reflective layer, the first side surface, and the second side surface while exposing the first light-emitting surface and the second light-emitting surface;
wherein the first light-emitting unit and the second light-emitting unit are able to emit different colors;
wherein, in a cross-sectional view, the first side surface has a first side portion facing the second light-emitting unit and the second side surface has a second side portion facing the first light-emitting unit, the light-absorbing layer has a first thickness and a second thickness between the first side portion and the second side portion, the first thickness is located farther away from the first side portion than the second thickness, and the first thickness is smaller than the second thickness.
