摘要： A light source device includes a plurality of light emitting elements, phosphor layers provided for each of the plurality of light emitting elements at positions on emission sides of light from the light emitting elements and parts of which are in contact with the light emitting elements, light shielding layers different from the phosphor layers, and reinforcement layers provided between the light emitting elements.

摘要： 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.
