TRANSPARENT SUBSTRATE WITH ANTIFOULING FILM

摘要

PROBLEM TO BE SOLVED: To provide a transparent substrate with an antifouling film that improves durability of the antifouling film while having anti-glare properties.SOLUTION: A transparent substrate with an antifouling film is provided which includes: a transparent substrate having a first principal plane and a second principal plane facing the first principal plane and subjected to anti-glare processing on the surface of the first principal plane; and a fluorine-containing organosilicon compound coat which is an antifouling film installed on the first principal plane-side of the transparent substrate. The surface roughness RMS of the first principal plane is 0.05 μm or more and 0.25 μm or less, and the average length RSm of elements of a roughness curve is 10 μm or more and 40 μm or less.SELECTED DRAWING: Figure 1
