Abstract
A method for manufacturing an image display device includes: providing a semiconductor growth substrate comprising a semiconductor layer on a first substrate, the semiconductor layer comprising a light-emitting layer; providing a second substrate comprising a circuit, wherein the circuit comprises a circuit element; forming a light-shielding layer on the second substrate; forming an insulating film on the light-shielding layer; bonding the semiconductor layer to the second substrate on which the insulating film is formed; forming a light-emitting element by etching the semiconductor layer; forming an insulating layer that covers the light-emitting element; and electrically connecting the light-emitting element to the circuit element. The light-shielding layer is located between the light-emitting element and the circuit element. In a plan view, the light-shielding layer covers the circuit element.
