| 摘要 |
A double-hetero structure light emitting diode using group III nitride compound semiconductor is disclosed- The diode has a first electrode connected to a first semiconductor layer and a second electrode connected to a second semiconductor layer. In one aspect of the invention, the first electrode is also connected to the second semiconductor layer. In another aspect of the invention, a resistance is disposed between the first electrode and the second semiconductor layer. In another aspect of the invention, a diode in a reverse direction and in parallel to the light emitting diode is disposed between the first and second electrodes.
