Abstract
Disclosed herein is a light-emitting element including: a first conductivity type semiconductor layer; a light-emitting functional layer formed on the first conductivity type semiconductor layer; a second conductivity type semiconductor layer formed on the light-emitting functional layer; a first conductivity type electrode which has continuity with the exposed portion of the first conductivity type semiconductor layer; a second conductivity type electrode which has continuity with the second conductivity type semiconductor layer; an insulating layer which lies between the light-emitting functional layer, second conductivity type semiconductor layer and second conductivity type electrode on one part and the first conductivity type electrode on the other part; and an annex insulating layer annexed to the insulating layer to form a virtual diode having rectifying action in the opposite direction to that of a diode made up of the second conductivity type semiconductor layer, light-emitting functional layer and first conductivity type semiconductor layer.
