Abstract: An electrode structure for effectively improving the stability of a semiconductor LED includes a reflecting layer capable of current spreading. In such an electrode structure, the current injects from the side surface of the reflecting layer to form a certain potential gradient over the contact surface between the electrode and the LED contact surface, thereby inhibiting the metal ion of the reflecting layer from migration due to electric field during usage, thereby improving device stability. In addition, the electrode portion for current injection can include a high-reflectivity material yet not vulnerable to ion migration, thereby increasing the entire reflecting area and improving luminous efficiency.
