Title:
METHOD FOR MANUFACTURING IMAGE DISPLAY DEVICE, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/209764
Kind Code:
A1
Abstract:
A method for manufacturing an image display device according to an embodiment comprises: a step for forming a first section of a single crystal metal on a substrate; a step for forming, on the first section, a semiconductor layer that includes a light-emitting layer; a step for processing the semiconductor layer to form a light-emitting element that includes a light-emitting surface on the first section; a step for forming a first insulating film that covers the substrate and the light-emitting element; a step for forming a circuit element on the first insulating film; a step for forming a light-blocking member between the circuit element and the light-emitting element; a step for forming a second insulating film that covers the first insulating film and the circuit element; a step for forming a first via penetrating the first and second insulating films; a step for forming a wiring layer on the second insulating film; a step for removing the substrate; and a step for removing at least a portion of the first section.
