LIGHT-EMITTING DIODE AND DEPOSITION APPARATUS FOR FABRICATING THE SAME

摘要

There is provided a light-emitting diode including: a first electrode including a reflective metal layer and a transparent conductive material layer formed on the reflective metal layer; an emitting material layer formed on the first electrode and including a light-emitting layer formed with a host and first and second dopants; and a second electrode formed on the emitting material layer and being a semi-transparent electrode, wherein a first wavelength corresponding to a peak value of a photo luminescence (PL) spectrum of the first dopant is shorter than a second wavelength corresponding to a peak value of an electro luminescence (EL) spectrum of the first dopant, and a third wavelength corresponding to a peak value of a PL spectrum of the second dopant is longer than a fourth wavelength corresponding to a peak value of an EL spectrum of the second dopant.
