1. A light-emitting element comprising:
a supportive substrate; a reflective layer formed on the supportive substrate; a transparent layer formed on the reflective layer; a light-emitting stacked layer comprising an active layer formed on the transparent layer; an etching-stop layer formed under the transparent layer and between the transparent layer and the reflective layer, wherein a lateral surface of the etching-stop layer is covered by the reflective layer; and a plurality of contact parts formed between the light-emitting stacked layer and the transparent layer, and devoid of passing through the active layer. |
