Abstract
An image display device manufacturing method according to an embodiment includes preparing a semiconductor layer, joining the semiconductor layer to a first substrate with a first metal layer interposed therebetween, bonding the semiconductor layer to a light-transmitting substrate, removing the first substrate, etching the semiconductor layer to form a light-emitting element including a light-emitting surface and an upper surface, etching the first metal layer to form a light-blocking electrode covering the upper surface, forming a first insulating film covering the light-emitting element and the light-blocking electrode, 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 passing through the first insulating film and the second insulating film, and forming a first wiring layer on the second insulating film.
