    • An antireflection structure having a high antireflection effect is provided.An antireflection structure (50) reduces reflection of light having a wavelength equal to or larger than a predetermined wavelength, and absorbs the light whose reflection is reduced. The antireflection structure (50) includes a base structure portion (7) which is configured to have a plurality of structural units (70) arranged on a reference plane, and each having a tilted surface (71) so that an angle between the first side surface (71) and a reference plane (51) is a predetermined angle, and a plurality of fine concave/convex portions (8, 8, . . . ) which are formed on a surface of the base structure portion (7), and arranged within a cycle equal to or smaller than the predetermined wavelength.
    • 提供了具有高抗反射效果的抗反射结构。 抗反射结构(50)减少了具有等于或大于预定波长的波长的光的反射,并且吸收反射减小的光。 防反射结构(50)包括基部结构部(7),该基部构造部(7)被配置为具有布置在基准平面上的多个结构单元(70),并且各自具有倾斜表面(71),使得第一侧 表面(71)和参考平面(51)是预定角度,并且形成在基部结构部分(7)的表面上的多个精细凹凸部(8,8 ...)和 布置在等于或小于预定波长的周期内。
