A light-emitting device includes a light-emitting loop unit and an open-circuit preventing unit. The open-circuit preventing unit and the light-emitting loop unit are in parallel connection. The light-emitting loop unit is driven by a first driving voltage, and the open-circuit preventing unit is driven by a second driving voltage. The second driving voltage is greater than the first driving voltage.
