摘要：
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.
