Abstract:
The translucent structure of the present invention has a haze of higher than 10% and at most 70% and has a concavo-convex structure on its surface. The concavo-convex structure has first convex portions having a diameter of larger than 10 μm in a cross section at a height of 0.05 μm+the bearing height of a surface shape, and second convex portions having a diameter of larger than 1 μm in a cross section at a height of 0.5 μm+the bearing height. The average diameter of the first convex portions is larger than 10 μm and at most 185 μm in a cross section at a height of 0.05 μm+the bearing height. The maximum height of the first convex portions is from 0.2 to 8 μm. The number of the second convex portions is from 0.0004 to 1.2 per 1 um2.
