Abstract
The invention provides a high luminance light-emitting diode capable of reducing the loss of light emitted from LED chips in a package and also capable of improving the light extraction efficiency from the package, wherein the light-emitting diode (1) includes a compound semiconductor layer (2) including a light-emitting portion (8) having a light-emitting layer (9) and a substrate (3), in which an external reflection layer (4) having a reflectivity higher than that of the substrate (3) is provided on a side surface of the substrate (3).
Claims13
A light-emitting diode, comprising a compound semiconductor layer which includes a light-emitting portion having a light-emitting layer and a substrate,
- wherein an external reflection layer having a reflectivity higher than that of the substrate is provided on a side surface of the substrate.
A method for manufacturing a light-emitting diode, comprising:
- a process in which a compound semiconductor layer including a light-emitting portion having a light-emitting layer is formed on a semiconductor substrate;
- a process in which the compound semiconductor layer and the substrate are joined;
- a process in which the semiconductor substrate is removed;
- and
- a process in which an external reflection layer is formed on a side surface of the substrate.
