Antiglare film-attached substrate, image display apparatus, and digital signage

An antiglare film-attached substrate comprising:

• a substrate comprising a first principal surface, a portion of the first principal surface being exposed;
• and
• an antiglare film covering another portion of the first principal surface, wherein
• the antiglare film-attached substrate comprises a second principal surface having unevenness and formed of the first principal surface and the surface of the antiglare film,
• when the second principal surface is viewed in plan, the area of the antiglare film accounts for 10 to 90% of the area of the second principal surface, and
• for the second principal surface, the arithmetic average roughness Ra, the maximum height Rz, and the average length RSm of roughness profile elements, as defined in Japanese Industrial Standards (JIS) B 0601-2001, satisfy the following requirements (i), (ii), and (iii):
• (i) the arithmetic average roughness Ra is 0.08 to 2 μm;
• (ii) the maximum height Rz is 0.5 to 15 μm;
• and
• (iii) the average length RSm of roughness profile elements is 15 to 50 μm.
