LIGHT EMITTING DIODE CHIP AND LIGHT EMITTING DEVICE HAVING THE SAME |
| 摘要 |
A light emitting diode (LED) chip can include: a first pattern region having one or more curved parts; and a second pattern region at least partially surrounding the first pattern region. The first pattern region can include a first conductive type nitride-based semiconductor layer, an active layer, a second conductive type nitride-based semiconductor layer, a top electrode layer, and a top bump layer stacked over a substrate, the second pattern region can include a first conductive type nitride-based semiconductor layer, a bottom electrode layer, and a bottom bump layer stacked over the substrate, and the first pattern region can include one or more protrusion patterns formed in the one or more curved part. |
