Abstract

An image display device includes a drive circuit substrate, micro LED elements, and a wavelength conversion layer that converts excitation light emitted from the micro LED elements and that emits converted long-wavelength light to a side opposite to the drive circuit substrate, the micro LED elements and the wavelength conversion layer being sequentially stacked on the drive circuit substrate. The micro LED elements include a first multilayer film that reflects the long-wavelength light converted by the wavelength conversion layer.
