<P>PROBLEM TO BE SOLVED: To provide a manufacturing method for a polarizing film which has uniform intra-plane optical characteristics and excellent optical characteristics and is produced from an raw film made of a polymer film, the polarizing film obtained by this producing method, an optical film formed by laminating this polarizing film and another optical layer, and an image display device constituted by applying the polarizing film or optical film. <P>SOLUTION: In at least one of a series of producing stages for producing the polarizing film, the ratio (L/W) of an initial raw film width (W) to an inter-stretching distance (L) in a processing stage including a stretching process is 0.5 to 30. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
