Title:
NON-TRANSPARENT FILM ATTACHED MEMBER
Document Type and Number:
WIPO Patent Application WO/2018/154915
Kind Code:
A1
Abstract:
A non-transparent film attached member is provided with a transparent substrate and a non-transparent film provided on the transparent substrate. In a surface shape obtained by measuring a (101 μm to 111 μm) × (135 μm to 148 μm) region with a laser microscope, the non-transparent film includes first convex parts with a diameter of more than 10 μm in a cross section at a first height level H1, and second convex parts with a diameter of 1 μm or more and 10 μm or less in a cross section at a second height level H2 in the surface shape. A maximum height of the first convex parts relative to a height of the lowest portion within the region is 8 μm to 30 μm, and an average height of the second convex parts relative to the second height level H2 is 0.1 μm to 3 μm. The number of the second convex parts is 0.001 to 0.05 per 1 μm2. The second convex parts account for 1% to 3% of the area of the region. In the non-transparent film, the ratio of Zr to Si (atomic ratio) is in the range of 0.003 to 0.04.
