Image display apparatus

An image display apparatus including a light emitting device, the light emitting device comprising:

• a light emitting element that emits blue light;
• a Mn2+-activated γ-AlON phosphor that emits green light in response to excitation by the blue light;
• and
• a Mn4+-activated phosphor that emits red light in response to excitation by the blue light, wherein
• the green light emitted by the Mn2+-activated γ-AlON phosphor has an emission-spectrum peak wavelength of not less than 522 nm and not more than 524 nm,
• the green light emitted by the Mn2+-activated γ-AlON phosphor has an emission-spectrum half width of not less than 38 nm and not more than 42 nm,
• the Mn2+-activated γ-AlON phosphor has a Mn concentration of not less than 2.4 wt % and not more than 3.02 wt % in a crystal of the Mn2+-activated γ-AlON phosphor,
• the Mn2+-activated γ-AlON phosphor and the Mn4+-activated phosphor are dispersed in one dispersion medium,
• the dispersion medium includes a scattering material that scatters the blue light emitted by the light emitting element, and
• a coverage is not less than 98%, the coverage being a ratio of an area covered within a color gamut of the image display apparatus with respect to an area of an Adobe RGB color gamut.
