Abstract:
A light emitting device having a circuit protection unit is provided. The circuit protection unit has a low-resistance layer and a potential barrier layer, wherein a barrier potential exists at the interface between the low-resistance layer and the potential barrier layer. The circuit protection unit is electrically connected with the light emitting device. When an electrostatic discharge or excessive forward current is occurred in the light emitting device, the circuit protection unit provides a rectifying function for preventing damages caused by static electricity or excessive forward current to the light emitting device.
