Abstract
Provided is an illumination device that makes it possible to enhance utilization efficiency of light, and a display device that includes the illumination device. The illumination device includes: a light source that is configured to generate light of a first wavelength; a luminescent body that is configured to wavelength-convert the light of the first wavelength to light of a second wavelength, the second wavelength being different from the first wavelength; and a wavelength selective filter that is provided on a light-incident side of the luminescent body, the wavelength selective filter being configured to transmit the light of the first wavelength and to reflect the light of the second wavelength.
