Abstract

A light-emitting device includes: a light-emitting mesa structure having a first top surface and a peripheral surface connected to the first top surface; a transparent conductive layer that is disposed on the first top surface and that has a second top surface; a first insulating structure that is at least disposed on the peripheral surface and that has a third top surface and an inner tapered surface indented from the third top surface, the inner tapered surface having an acute angle with respect to the second top surface; and a reflective layer that is disposed on the transparent conductive layer and that has a first side surface in contact with the inner tapered surface. A method for manufacturing the light-emitting device is also disclosed.
