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.

Image display device

A photodetector measures flight time by an imaging optical element imaging reflected light from an illuminated illumination region of an object illuminated by pulse light, and a light detection portion receiving the imaged light. The light detection portion is formed larger than a projection region reflected at the illumination region of the object and imaged on the light detection portion. In the light detection portion, a portion overlaying the projection region is activated as a light-detection region.
