Title:
光反応性重合体およびこれを含む配向膜
Document Type and Number:
Japanese Patent JP5870091
Kind Code:
B2
Abstract:
Disclosed therein are a photoreactive polymer, and an alignment layer comprising the same that exhibit excellences in alignment rate and alignment stability. The photoreactive polymer comprises a cyclic olefin-based repeating unit with at least one photoreactive substituent, and the maximum absolute value of a variation in dichloric ratio per unit UV dose as given by d(dichloric ratio)/d(mJ/cm 2 ) upon exposure to a polarized UV radiation having a wavelength of 150 to 450 nm at a total exposure dose of 20 mJ/cm 2 or less is at least 0.003.
