Abstract
A quantum dot light-emitting diode includes a substrate, an anode electrode layer, a cathode electrode layer, a light-emitting layer, and an electron blocking layer. The anode electrode layer is disposed on the substrate. The cathode electrode layer is disposed on the anode electrode layer. The light-emitting layer is disposed between the cathode electrode layer and the anode electrode layer. The light-emitting layer includes a plurality of first particles. The electron blocking layer is disposed between the light-emitting layer and the anode electrode layer. The electron blocking layer includes a plurality of second particles. The first particles and the second particles are quantum dots. A size of the second particles is smaller than a size of the first particles.
