Light-emitting element

Abstract

A light-emitting element includes: an anode; a cathode provided across from the anode; and a light-emitting layer provided between the anode and the cathode, and containing first quantum dots and second quantum dots, the first quantum dots each having a core-shell structure including a first core and a first shell provided on a surface of the first core, and the second quantum dots each having a core-shell structure including a second core and a second shell provided on a surface of the second core. A CBM of the first shell is lower than a CBM of the second shell, and a VBM of the first shell is lower than a VBM of the second shell.
