Abstract
A light-emitting element is provided with the following: a first electrode and a second electrode; and a quantum dot layer disposed between the first electrode and the second electrode, and including first quantum dots. The quantum dot layer includes a space absent from the first quantum dots penetrating the quantum dot layer in a thickness direction of the quantum dot layer. The space contains second quantum dots having a smaller particle diameter than the first quantum dots.
