WIPO Patent Application WO/2017/135261
Kind Code:
A1
Abstract:
In order to provide a translucent structure having a low haze factor and low glare, the present invention provides a translucent structure having an uneven structure on the surface thereof, the uneven structure including first projections 5a having a diameter of 1 µm or greater at a height of 0.05 µm above the a surface shape (a) bearing height obtained by measuring the uneven structure using a laser microscope, the average value of the diameter of the first projections 5a being 1.000-16.000 µm, a plurality of projections in an image (c) in which the plurality of projections are scattered including second projections 5b having a diameter of 0.4 µm or greater at a height of 0.01 µm when 0 is used as the bearing height, the image (c) being obtained by obtaining a smoothing image (b) by filtering of the surface shape (a) by image processing software and subtracting XYZ data of the smoothing image (b) from XYZ data of the surface shape (a), the density of the second projections 5b being 0.023-7.210/µm2, and the ratio of the total area of a cross-section of the second projections 5b at a height of 0.01 µm being 0.900-90.000%.
