A display device of the present invention includes a red-light-emitting element (1), a green-light-emitting element (2), and a blue-light-emitting element (3). The red-light-emitting element (1) and the green-light-emitting element (2) each include an organic EL section (20) and a color converting layer (15). The color converting layer (15) has an optical distance that extends from (i) a position of the color converting layer from which position light is emitted to (ii) an extraction surface of the color converting layer, the optical distance being varied between the red-light-emitting element (1) and (2). The blue-light-emitting element (3) may include a film-thickness adjusting layer (19) instead of the color converting layer (15).
