Abstract
A quantum dot light emitting diode and a method for fabricating the same. The quantum dot light emitting diode includes: a substrate, a bottom electrode, a light-emitting function layer, and a top electrode. A functional layer is formed by the bottom electrode, the light-emitting function layer, and the top electrode; and an outer surface of the functional layer is provided with a first protective layer. The first protective layer is made from a fluoro-acrylate copolymer, which has hydrophobicity, good light transmittance, flexibility, and heat dissipation, and can effectively prevent moisture and oxygen from penetrating into an internal structure of the quantum dot light emitting diode, thereby having a good protection effect, and in the meanwhile, the quantum dot light emitting diode can dissipate heat timely, which is beneficial for the device to keep its performance, improve light-emitting efficiency, and the service life.
