The invention discloses a quantum dot film and a backlight module. The quantum dot film comprises a quantum dot layer, wherein the quantum dot layer comprises a matrix and multiple quantum dots which are uniformly dispersed in the matrix; multiple diffusion particles which are uniformly dispersed are arranged in the matrix; a refractive index difference between the diffusion particles and the matrix is more than 0.01; the diffusion particles are used for scattering incident rays in the matrix; an optical path through which the rays pass the quantum dot layer is increased. According to the quantum dot film, the optical path through which the rays pass the quantum dot layer can be increased, the quantum dot utilization rate is increased, the light conversion efficiency is improved, and the cost is reduced. Moreover, three effects of light conversion, atomization and brightness enhancement can be provided, and the thickness of the backlight module is reduced.
