Abstract
A light-emitting element producing method includes: a step of forming a first-charge transport layer on a first electrode; a step of applying a first photosensitive resin composition, containing first quantum dots, to the first-charge transport layer, and forming a first-quantum-dot containing layer; a step of applying a second photosensitive resin composition, containing second quantum dots, to the first-quantum-dot containing layer, and forming a second-quantum-dot containing layer; a step of forming a second-charge transport layer on the second-quantum-dot containing layer; and a step of forming a second electrode on the second-charge transport layer.
