    摘要: An optical sheet having both of an excellent light condensing function and an excellent scratch resistance is provided. An optical sheet (40) includes: a sheet-like main body (45); at least three or more first unit shaped elements (50) arranged on one surface (46) of the main body; and second unit shaped elements (55) arranged on the one surface of the main body. Each of the second unit shaped elements extend in parallel with in one direction on a sheet surface of the main body. A height H1 of each of the first unit shaped elements from the one surface is higher than a height H2 of each of the second unit shaped elements. A rate of an area occupied by the first unit shaped elements on the one surface is not more than 10.0%, when observed along a normal direction nd relative to the one surface.

    摘要: An optical sheet including a fly-eye lens is provided. This optical sheet can exhibit excellent optical functions, including desired light condensing ability, light diffusing ability and ability for rendering a light source image substantially invisible, as well as can be produced with high reproducibility. In one example, the optical sheet (40) includes: a sheet-like main body (45); first unit shaped elements (50) arranged on one surface (46) of the main body and constituting together the fly-eye lens; and second unit shaped elements (55) arranged on the one surface of the main body and extending in parallel with one direction on the sheet surface of the main body. In this case, the first unit shaped elements are arranged, with a space provided therebetween, on the one surface of the main body, while the second unit shaped elements are arranged, between the first unit shaped elements, on the one surface of the main body.

    摘要: An optical sheet includes a sheet-like body portion, and unit prisms arranged on one surface of the body portion. Each unit prism extends linearly in a direction intersecting the arrangement direction. Each unit prism, when viewed in a direction parallel to the arrangement direction of the unit prisms, has an uneven polygonal-line-shaped contour and, with reference to raised portions defined by the polygonal-line-shaped contour of each unit prism, the distance between a top of each raised portion, a farthest point from the body portion in the raised portion, and the body portion in the normal direction of the body portion is not constant. The optical sheet can prevent significant problems when it is superimposed on another member.

    摘要: An optical sheet including a body portion, unit optical elements arranged on one surface of the body portion, and an uneven coating having an uneven surface with micro-protrusions, provided on the other surface of the body portion. When the hardness He of the optical element surface Pe and the hardness Hm of the uneven coating surface Pm are evaluated in terms of the pencil hardness measured in accordance with JIS K5600-5-4 (1999) (load: 1000 g; speed: 1 mm/s), the hardness Hm is not less than the hardness He (hardness Hm≧hardness He) and the hardness Hm is preferably not less than F. Further, the hardness He and the hardness Hm preferably satisfy the following relation: hardness He+3≧hardness Hm≧hardness He+2 wherein the expression “He+1” indicates a hardness harder than He by one unit on the pencil hardness scale.
