Abstract
A method for manufacturing an image display device including providing a plurality of first subpixels and a second subpixel, where the plurality of first subpixels have a plurality of first light-emitting elements and are configured to emit red, green, and blue light, and the second subpixel has a second light-emitting element and being configured to emit blue light. A defective subpixel detection process includes turning on the plurality of first light-emitting elements, and acquiring data of position of at least one defective subpixel among the plurality of first subpixels, where the defective subpixel is supposed to emit predetermined light with a predetermined color. A wavelength conversion layer formation process includes providing a wavelength conversion layer over the second light-emitting element to convert emission light emitted from the second light-emitting element to the predetermined light with the predetermined color if the predetermined color is red or green.
