Disclosed is a quantum dot light emitting device including a ligand-substituted quantum dot light emitting layer with a polymer having amine groups. The introduction of the ligand-substituted quantum dot light emitting layer with a polymer having amine groups changes the energy level of an electron transport layer and enables control over the charge injection properties of the device so that the flow of electrons can be controlled. In addition, the ligand substitution is effective in removing oleic acid as a stabilizer of quantum dots to prevent an increase in driving voltage caused by the introduction of the additional material, achieving markedly improved efficiency of the device. Also disclosed is a method for fabricating the quantum dot light emitting device.
