An image display device includes: a substrate including a first surface; a graphene-including layer located on the first surface; a light-emitting element located on the graphene-including layer, the light-emitting element including: a bottom surface on the graphene-including layer, and a surface including a light-emitting surface, the light-emitting surface being a surface at a side opposite to the bottom surface; a first insulating film that covers the graphene-including layer, the first surface, and a lateral surface of the light-emitting element; a circuit element located on the first insulating film; a second insulating film that covers the first insulating film and the circuit element; a via extending through the first and second insulating films; and a wiring layer located on the second insulating film.
