A light diffusing film is produced by preparing a paint by adding a light transmissive diffusing material comprising resin beads to a light transmissive resin, and coating the paint on one or both of the surfaces of transparent film substrate made of TAC, to produce a light diffusing layer. In the light diffusing film, the haze value on the surface of light diffusing layer is three or more, the difference between the haze value along the normal and that the lines ±60° apart from the normal is four or less, and the surface is practically smooth whose roughness is so adjusted as to give a surface roughness Ra of Ra<=0.2 mum. Application of such a light diffusing film onto a display panel inhibits scattering reflection which would otherwise cause the display to be whitish, reduces the variation of haze values which vary depending on the viewed angle, and thus improves display quality.
