Abstract
A chip-scale package type light emitting diode is provided. In the light emitting diode according to one embodiment, an opening exposing a pad metal layer is separated from an opening of a lower insulation layer which exposes an ohmic reflection layer formed on a mesa. Therefore, it is possible to prevent solder, particularly Sn, from diffusing and contaminating the ohmic reflection layer.
