A method of producing an antireflection structure for use on a display or a window
surface or both in an electronic device, such as a mobile phone. The display can
be an LCD with a top polarizer and a bottom polarizer. The antireflection structure
is imparted on the top polarizer by a roller embossing process. In particular,
the embossing is carried out in the same manufacturing process when the polarizer
is produced. The antireflection structure has a plurality of sub-wavelength periodic
grooves. The antireflection structure on the window surface can be imparted using
an embossing process or an injection molding process.
