Abstract
A method for manufacturing an image display device according to an embodiment includes: forming a graphene layer on a first surface of a substrate; forming a semiconductor layer on the graphene layer; forming a light-emitting element that includes a light-emitting surface on the graphene layer and an upper surface at a side opposite to the light-emitting surface by patterning the semiconductor layer; forming a first insulating film covering the first surface, the graphene layer, and the light-emitting element; forming a circuit element on the first insulating film; forming a second insulating film covering the first insulating film and the circuit element; forming a first via extending through the first and second insulating films; and forming a first wiring layer on the second insulating film. The first via is located between, and electrically connects, the first wiring layer and the upper surface.
