Abstract

A light-emitting element includes: a first electrode having a reflective surface that reflects light; a second electrode that transmits light; and a light-emitting layer between the first electrode and the second electrode, the light-emitting layer containing a first light-emitting material that emits first light that has a peak wavelength equal to a first wavelength and a second light-emitting material that emits second light that has a peak wavelength equal to a second wavelength shorter than the first wavelength, wherein the second light has at least one location where intensity is higher in a direction off a normal to the reflective surface than in the normal.
