| description | To provide a surface shape diffusion sheet, a reflective screen, a picture display system, and a method for displaying a picture which can reduce black floating.SOLUTION: A surface shape diffusion sheet 1 includes: a surface shape anisotropic diffusion layer 2; and a substrate 3 under the surface shape anisotropic diffusion layer. A diffusion angle of the surface shape anisotropic diffusion layer 2 in an in-plane vertical direction is ±14° (a half-band width), and a transmittance T in a visible light wavelength band in the substrate 3 or on the substrate 3 is in a range from 0.5 to smaller than 1. The picture display system calculates an amount of black floating, Lb (=255×[luminance of block color]/[luminance of white color]) of a picture and corrects reduction of brightness L observed in a brightness range Lb≤L |
