ANTIREFLECTION STRUCTURE, ANTIREFLECTION FILM EQUIPPED THEREWITH, LIGHT GUIDING MATERIAL, ILLUMINATOR AND LIQUID CRYSTAL DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide antireflection structure with which the visibility of a display part displayed by external light or illuminating light can be drastically enhanced by preventing the reflection of the external light or the illuminating light and to provide an antireflection film equipped with the antireflection structure, a light guiding material and a liquid crystal display.

SOLUTION: The antireflection structure 28 is equipped with many minute holes 19 having an aperture 20a along a 1st surface 18a and having bottom face 20b toward a 2nd surface 18b opposite to the 1st surface 18a and extended from the aperture 20a toward the bottom face 20b, and a projecting part 35 provided between the adjacent minute holes on the 1st surface side, then the apertures 20a are arranged zigzag along the 1st surface 18a, and the inner wall surface 20d of the hole 19 is formed to be more recessed to the 2nd surface side than an inclined surface 36 including a line linking the deepest point (d) in the hole and the apex of the projecting part 35 adjacent to the hole 19.
