Abstract: A light-emitting device is provided. The light-emitting device includes a circuit board and a connection board disposed on the circuit board and having a first pad, a second pad, and a third pad. The light-emitting device also includes a first light-emitting element disposed on the connection board and having a first electrode and a second electrode and a second light-emitting element adjacent to the first light-emitting element and having a third electrode and a fourth electrode. The light-emitting device further includes a light-converting layer disposed on the first light-emitting element and the second light-emitting element. The thermal expansion coefficient of the connection board is smaller than the thermal expansion coefficient of the circuit board.
