Ultrathin (<200nm) azo dye polarizing film with high optical performance is developed by photo-alignment methods. The dichroic ratio is as high as over 100, the polarization efficiency is more significant than 99%. The photostability of photoaligned azo dye film must be improved to be stable against polarized and non-polarized illumination.
