<p>PROBLEM TO BE SOLVED: To provide a light-emitting element capable of reducing generation of high-frequency ripples in an interference filter configured by four reflection interfaces.SOLUTION: A light-emitting element comprises: a first electrode 31; a second electrode 32; and an organic layer 33 provided between the first electrode 31 and the second electrode 32, and configured by laminating a first light-emitting layer 34 and a second light-emitting layer 35 from the first electrode side. Light from the organic layer 33 is reflected at a first reflection interface between the first light-emitting layer 34 and the first electrode 31, passes through the second electrode 32, and then, is emitted to the outside. At an opposite side of the second light-emitting layer 35 to the first light-emitting layer 34, a first optical transparent layer 41, a second optical transparent layer 42, and a third optical transparent layer 43 are provided from the second light-emitting layer side. The positions of the first reflection interface, a second reflection interface, a third reflection interface, and a fourth reflection interface are defined on the basis of a predetermined condition.</p> |
