    摘要: [Problem] Provided is a transparent screen which satisfies both the visibility of the projection light and the transmission light by anisotropically scattering and reflecting the projection light emitted from a light source.[Solving means] A transparent screen according to the present invention comprises a light diffusion layer including a binder and microparticles, said transparent screen having a scattered light brilliance profile characterized to meet the following conditions A to C: A: the emitted light relative brilliance in the 0° direction is from 50 to 95, when the entered light relative brilliance is 100; B: the emitted light relative brilliance in the ±5° direction is 1.1 or less, when the emitted light relative brilliance in the 0° direction is 100; and C: the emitted light relative brilliance in the ±50° direction is 0.0005 or higher, when the emitted light relative brilliance in the 0° direction is 100; when the brilliance is Y from the XYZ color system measured with a goniophotometer.
