A light-emitting element includes a first electrode, a second electrode, a light-emitting layer between the first electrode and the second electrode, and an intervening layer between the first electrode and the light-emitting layer, the intervening layer containing an oxide. The first electrode includes: a first layer adjacent to the intervening layer, the first layer containing atoms of a first metal element; and a second layer containing atoms of a second metal element, the first layer and the second layer are stacked in a stated order when viewed from the light-emitting layer, and the second metal element is more susceptible to oxidation than the first metal element.
