The present invention provides a light wavelength conversion composition and a light wavelength conversion member having excellent heat resistance and heat and moisture resistance. Moreover, while having excellent heat resistance and heat-and-moisture resistance, a barrier member can be omitted, or even when a barrier member is used, a light wavelength conversion sheet that can suppress dotted luminance defects, such a light wavelength conversion member or Provided are a backlight device and an image display device provided with a light wavelength conversion sheet. [Solution] According to one aspect of the present invention, there is provided a light wavelength conversion composition, which is a light wavelength conversion composition, comprising a quantum dot and a specific phosphine compound. .
