Abstract:
Disclosed is a light emitting diode (LED) for enhancing the current spreading performance. The LED includes a plurality of contact holes exposing an N-type semiconductor layer through a P-type semiconductor layer and an active layer, and a connection pattern electrically connecting exposed portions of the N-type semiconductor layer through the contact holes, thereby enhancing current spreading in the N-type semiconductor layer. In addition, disclosed is an LED including a plurality of light emitting cells spaced apart from one another on an N-type semiconductor layer and an N-contact layer between the light emitting cells. A plurality of light emitting cells are employed in the LED, so that current can be spread in the LED.
