Light emitting diode and display device comprising the same
A light emission element includes a first semiconductor layer, a light emission layer, and a second semiconductor layer. The first semiconductor layer in the light emission portion is provided with a concave portion having a concave shape. The light emission layer and the second semiconductor layer disposed on the first semiconductor layer are also disposed along the concave shape of the concave portion. The light emitting layer disposed along the shape of the concave portion emits light by electrons and holes injected from the first semiconductor layer and the second semiconductor layer. Further, the light path of the light emitted according to the concave shape is adjusted. Therefore, a light emission element having improved light efficiency and a display device using the same can be provided.
