Document Type and Number:
WIPO Patent Application WO/2017/061493
Kind Code:
A1
Abstract:
Provided is an optical sheet that has excellent anti-glare properties, contrast, and image clarity, and can display dynamic moving images. This optical sheet has at least one surface that is a textured surface, and the ten-point average roughness Rz0.8 determined in accordance with JIS B0601:1994 with a cutoff value of 0.8 mm, the ten-point average roughness Rz0.25 determined in accordance with JIS B0601:1994 with a cutoff value of 0.25 mm, and the standard deviation (SD) of the arithmetic mean roughness Ra0.8 determined in accordance with JIS B0601:1994 with a cutoff value of 0.8 mm of the textured surface satisfy conditions (1) to (3). (1) 0.300 μm ≤ Rz0.8 ≤ 0.650 μm; (2) 0.170 μm ≤ Rz0.25 ≤ 0.400 μm; (3) SD ≤ 0.015 μm.
