LIGHT EMITTING DIODE AND FABRICATING METHOD THEREOF

摘要

A light emitting diode and a manufacturing method thereof are provided to emit light of various colors by using a simple and economical method, without performing an additional heat treatment process. An active layer(50) is interposed between a first barrier layer(40) and a second barrier layer(60), and has a quantum dot layer with plural quantum dots distributed in a surface direction, and an intermediate thin film layer(30) enclosing the quantum dots of the quantum dot layer. A part or all of the quantum dots of the quantum dot layer have a distribution patter similar to that of an adjacent quantum dot layer. A wavelength of the light emitted from the quantum dot layer is longer than that of the light emitted from the intermediate thin film layer.
