Title:
METHOD FOR PRODUCING IMAGE DISPLAY DEVICE, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/209748
Kind Code:
A1
Abstract:
According to one embodiment, this method for producing an image display device comprises: a step for forming a graphene layer on a first surface of a substrate; a step for forming a semiconductor layer on the graphene layer; a step for machining the semiconductor layer to form a light-emitting element which includes a light-emitting surface on the graphene layer and an upper surface on the reverse side from the light-emitting surface; a step for forming a first insulating film which covers the first surface, the graphene layer and the light-emitting element; a step for forming a circuit element on the first insulating film; a step for forming a second insulating film which covers the first insulating film and the circuit element; a step for forming a first via which passes through the first insulating film and the second insulating film; and a step for forming a first wiring layer on the second insulating film. The first via is provided between the first wiring layer and the upper surface and electrically connects the first wiring layer and the upper surface.
