Abstract: A light-emitting device includes a light-emitting element, and a covering layer. The light-emitting element includes a top surface, a bottom surface, a light-emitting stack between the top surface and the bottom surface, and an adhesion enhancing layer surrounding the light-emitting stack. The covering layer covers the light-emitting element and contacts the adhesion enhancing layer. Moreover, the adhesion enhancing layer includes an oxide and a thickness greater than 5 nm and less than 1000 nm.
