The objective of the invention is to provide a wavelength conversion film demonstrating a high optical density, a wavelength conversion film forming composition used suitably for forming the wavelength conversion film, and a production method for a cluster-containing quantum dot that may be applied suitably to the wavelength conversion film and the wavelength conversion film forming composition. In this invention, for a wavelength conversion film containing a quantum dot converting blue light into red light or green light, the light beam transmittance of the wavelength conversion film at 450 nm wavelength is set to 40% or lower, the light beam transmittance of the wavelength conversion film at 650 nm wavelength is set to 90% or higher if the hue of the light beam after the wavelength conversion is red, and the light beam transmittance of the wavelength conversion film at 550 nm wavelength is set to 90% or higher if the hue of the light beam after the wavelength conversion is green.
