Title:
QUANTUM DOT LIGHT EMITTING ELEMENT AND DISPLAY
Document Type and Number:
Japanese Patent JP2022036685
Kind Code:
A
Abstract:
To provide a quantum dot light emitting element with excellent element characteristics by suppressing leakage current caused by the electron injection layer in the quantum dot light emitting element using high color purity quantum dot materials.SOLUTION: A quantum dot light emitting element 10 includes an anode 30, a light emitting layer 50, an electron injection layer 60, and a cathode 70, in that order. The light emitting layer 50 contains quantum dots. The electron injection layer 60 contains nanoparticles and an electron transport material. It is preferred that the nanoparticles comprise nanoparticles containing zinc oxide.SELECTED DRAWING: Figure 1
