To provide a light diffusion sheet and a screen with which satisfactory color reproducibility is obtained while suppressing deterioration in light transmissivity.
The light diffusion sheet and (or) a colored sheet is constituted by dispersing light transmissive micro particles in a translucent base material and is characterized in that the light diffusion sheet and (or) colored sheet satisfies the following expression (1). -0.5%≤T1-T2≤5% ... (1) (in the expression, T1 indicates transmissivity (%) of light with wavelength of 450 nm and T2 indicates transmissivity (%) of light with wavelength of 600 nm). A light diffusion sheet and (or) colored sheet for a screen and the screen having the light diffusion sheet and (or) the colored sheet for the screen are provided.
