Abstract
To provide a translucent structure having a low haze factor and low sparkle. The translucent structure has an uneven structure at the surface thereof, wherein the uneven structure includes first convex portions, of which the diameters at a height of the bearing height+0.05 μm of the surface shape (a), obtainable by measuring the uneven structure by a laser microscope, are at least 1 μm, and in an image (c) in which a plurality of convex portions are scattered, obtained by filtering the surface shape (a) by image processing software to obtain a smoothing image (b), and subtracting XYZ data of the smoothing image (b) from XYZ data of the surface shape (a), said plurality of convex portions include second convex portions, of which the diameters at a height of 0.01 μm when the bearing height is deemed to be 0, are at least 0.4 μm, the density of the second convex portions is from 0.023 to 7.210 units/μm, and the proportion of the total area in cross-section at a height of 0.01 μm of the second convex portionsis from 0.900 to 90.000%.
