Abstract
A quantum dot light-emitting diode and a display apparatus comprising the quantum dot light-emitting diode are provided. The quantum dot light-emitting diode comprises an anode, a hole injecting layer, a hole transporting layer, a quantum dot light-emitting layer, an electron transporting layer and a cathode from bottom to top, wherein the materials of the quantum dot light-emitting layer contain quantum dots and CuSCN nano-particles. By blending quantum dots and CuSCN nano-particles into a membrane to prepare a quantum dot light-emitting layer, a hole trap state on the surface of the quantum dots is passivated, and the transporting effect of a hole is improved, so that the injection of holes in the quantum dot light-emitting diode and that of electrons achieve balance, and thus the light-emitting efficiency and stability are improved.
