摘要： A cleaning solution is used, in a transparent antireflective structure that has, on one surface thereof, a plurality of convexities formed at a period equal to or shorter than wavelength in a visible light range, and that prevents, at the one surface, reflection of light entering the one surface, to clean a concavity defining a region between adjacent two of the plural convexities, the cleaning solution having a pH of 10.00 or more.

摘要： Disclosed are an anti-reflection structure, an imprint mold, methods for producing them and a display device capable of achieving appropriate visibility by forming regions different in reflection characteristics mixed in a film including a moth-eye structure, and sufficiently reducing reflection and sufficiently improving transmittance by the moth-eye structure. The anti-reflection structure includes a surface with an uneven structure composed of a transparent body and includes protrusions, the width between the tops of any pair of the adjacent protrusions being equal to or shorter than visible light wavelengths, the anti-reflection structure including a first region including a surface with the uneven structure, and a second region including a surface with a structure composed of a transparent body, the structure being different from the uneven structure and the second region in a plan view having a shape forming at least one selected from the group consisting of characters, symbols, and graphics.
