Abstract:
The electroluminescence device of the disclosure includes: a base material provided with a recessed portion; a light-emitting element including a reflective layer provided on the front surface of the recessed portion, a filling layer having optical transparency and filling an inside of the recessed portion with the reflective layer interposed therebetween, a first electrode having optical transparency provided on the filling layer, an organic layer including a light-emitting layer provided on the first electrode, and a second electrode having optical transparency provided on the organic layer, and an active element connected to the light-emitting element, wherein a display region includes a plurality of unit regions divided from one another, the unit regions include a plurality of the light-emitting elements and the active elements configured to control the light emission of the plurality of light-emitting elements, and the reflective layer of at least one of the light-emitting elements of the plurality of recessed portions functions as a contact portion with the active element.
