    Abstract: An optical body including: a first optical layer which has a surface having a convex profile in which a plurality of one-directionally extending elongated convex portions are one-dimensionally aligned in one direction; an inorganic layer disposed on the surface of the first optical layer on a side having the convex profile and a second optical layer disposed on a side of the inorganic layer so that the convex profile is embedded; wherein the convex profile meets at least one of the following (1) to (4): (1) a height varies in an extending direction in each of the elongated convex portions, (2) a ridge portion meanders in a direction perpendicular to both the extending direction and a height direction of the convex portion in each of the elongated convex portions, (3) heights of the elongated convex portions adjacent to each other are different from each other, and (4) a triangular prism-shaped convex portion and an elongated convex portion having a curved surface are adjacent to each other.

    Abstract: The purpose of the present invention is to prevent an increase in reflectance and a decrease in transmittance, retain the intact instantaneousness and ease of stripping, improve the releasability of the adhesive, avoid the generation of distortion due to the thickness of the adhesive, and ensure the visibility, by laminating filmy members (10) each equipped with a moth-eye structure (12). This transparent laminate (1) comprises a plurality of filmy members (10) which each comprise a base (11) and, disposed on at least one surface thereof, a structure (12) made up of recesses and protrusions which have been regularly arranged at a pitch not longer than the wavelengths of visible light. At least the ends of the filmy members (10) have been superposed, with a pressure-sensitive adhesive layer (2) interposed therebetween. In the superposed filmy members (10), there is a space (14) between the opposed structures (12).

    Abstract translation: 本发明的目的是防止反射率的增加和透射率的降低，保持完整的瞬时性和易剥离性，改善粘合剂的脱模性，避免由于粘合剂的厚度而产生变形，并确保 通过层压每个配备有蛾眼结构（12）的薄膜构件（10）可见度。 这种透明层压体（1）包括多个薄膜构件（10），每个薄膜构件（10）各自包括基部（11），并且在其至少一个表面上设置由凹部和突起构成的结构（12），所述凹部和突起被规则地布置在 不超过可见光波长的间距。 薄膜构件（10）的至少端部已经被叠置在其间插入压敏粘合剂层（2）。 在重叠的薄膜构件（10）中，在相对的结构（12）之间存在空间（14）。
