A light-emitting element having an excavated shape inside one light-emitting region (13), and having at least one first trench section (41TR1) obtained by layering a first electrode (41), an EL layer (42) and a second electrode (43) in this order so as to contact one another, wherein a reflecting electrode is contained by the first electrode (41) and/or the second electrode (42), and the surface of the reflecting electrode on the EL layer (42) side thereof is provided with concavoconvex sections (41a, 43a) of the submicron order for diffracting surface plasmons. |
