Abstract

The present invention relates to a quantum dot light emitting element which can form a quantum light emitting layer configured of charge transporting particles and quantum dots and a charge transporting layer in a solution process, to reduce process expense, and a method for manufacturing the same. The quantum dot light emitting element includes a substrate, an anode formed on the substrate, a quantum light emitting layer formed on the anode, the quantum light emitting layer having charge transporting particles and quantum dots mixed therein, and a cathode formed on the quantum light emitting layer.
