Abstract:
A base with a low-reflection film includes: a transparent base; a low-reflection film formed on a first principal surface of the transparent base; and a black printed part formed on a part of a second principal surface of the transparent base opposite to the first principal surface, in which a luminous reflectance R of the base with the low-reflection film with respect to incident light from the low-reflection film side is 2% or less in a region of the transparent base having the black printed part, and a ratio R1/R2 between a luminous reflectance R1 of a surface of the low-reflection film and a luminous reflectance R2 at an interface of the black printed part with the transparent base is ⅙ or more.
