Polarizing film optically functional film laminate including polarizing film production method for optical film laminate including polarizing film and organic EL display device having polarizing film
Conventionally, a polarizing film having a thin and high transmittance has a problem of low durability. The present invention relates to a polarizing film of a continuous web comprising a polyvinyl alcohol-based resin containing potassium and oriented iodine, wherein the thickness of the polarizing film is 7 占 퐉 or less, the polarizing film has a single transmittance of 44.0% (I / K) of the iodine element (I) to the potassium element (K) contained in the polarizing film is 1.8 or more.
