Abstract: A light-emitting diode includes a base and light-emitting devices including a first light-emitting device, a second light-emitting device, and a third light-emitting device. The area of the first light-emitting device, the area of the second light-emitting device, and the area of the third light-emitting device decrease in order. Each light-emitting device includes a light-emitting stacked layer. In two adjacent light-emitting devices, at least one light-emitting device further includes a first reflective layer provided between a light-emitting stacked layer of the light-emitting device to which the first reflective layer belongs and another light-emitting device. The first reflective layer covers a first region and exposes at least a portion of a second region, the first region being a region where the two adjacent light-emitting devices overlap with each other, and the second region being a region where the two adjacent light-emitting devices are non-overlapping with each other.
