According to the invention, the optical film is processed into circular shape as stated above. Thus, optical members with high versatility can be produced without being affected by the optical film-specific optical axis, and optical members that allows easy inventory control can be provided with no reduction in production efficiency. And a method of processing a long size optical film into a circular shape, subsequently processing the optical film processed into the circular shape into an arbitrary shape, also allows a fine tuning of its optical axis even after it is produced from the long size optical film, therefore, optical members with a high degree of flexibility in design and with high versatility can be provided. |
