Light diffusion element

There is provided a light diffusing element having less unevenness in external appearance while having excellent light diffusibility (that is, having a high haze). A light diffusing element according to an embodiment of the present invention includes: a base material film; and a light diffusing film provided on one surface of the base material film, wherein: the light diffusing film has a haze value of 75% or more; the light diffusing film contains a fluorine-based surfactant; the fluorine-based surfactant is localized on a surface of the light diffusing film opposite to the base material film; and the fluorine-based surfactant contains at least one kind of constituent unit selected from the group consisting of a constituent unit represented by the following general formula (I), a constituent unit represented by the following general formula (II), and a constituent unit represented by the following general formula (III): in the general formula (I), m represents an integer of 1 to 10, and in the general formula (II), n represents an integer of 2 to 10.
