发光元件
摘要：
实施例涉及一种发光元件，该发光元件能够通过增加在第一电极和第一半导体层之间的接触面积使电流容易地扩展并且改进驱动电压，并且包括：发光结构，其包括第一半导体层、有源层和第二半导体层；凹槽，其通过底表面暴露第二半导体层并且并且通过去除发光结构经由侧表面暴露第一半导体层、有源层以及第二半导体层；第一电极，其被连接到在凹槽的底表面处暴露的第一半导体层；第一绝缘图案，其覆盖通过凹槽的侧表面暴露的第一半导体层、有源层和第二半导体层，所述第一绝缘图案具有的一端延伸到第一电极的上表面的一部分，并且具有的另一端延伸到第二半导体层的上表面的一部分，使得第一电极的上表面和第二半导体层的上表面被部分地暴露；第一反射层，其被布置在暴露的第二半导体层上；第二反射层，其用于暴露第二半导体层和第一电极；以及第二电极，其被布置在由第二反射层暴露的第二半导体层上。
摘要（英）：

An embodiment relates to a light-emitting element, which enables a current to be easily spread and a driving voltage to be improved by increasing a contact area between a first electrode and a first semiconductor layer, and comprises: a light-emitting structure including the first semiconductor layer, an active layer, and a second semiconductor layer; a groove exposing the second semiconductor layer through the bottom surface and exposing the first semiconductor layer, the active layer, and the second semiconductor layer through a lateral surface by removing the light-emitting structure; the first electrode connected to the first semiconductor layer exposed through the bottom surface of the groove; a first insulation pattern, which covers the first semiconductor layer, the active layer, and the second semiconductor layer exposed through the lateral surface of the groove, has one end extending up till a portion of the upper surface of the first electrode, and has another end extending up till a portion of the upper surface of the second semiconductor layer, such that the upper surface of the first electrode and the upper surface of the second semiconductor layer are partially exposed; a first reflection layer disposed on the exposed second semiconductor layer; a second reflection layer for exposing the second semiconductor layer and the first electrode; and a second electrode disposed on the second reflection layer exposed by the second reflection layer.
