Abstract
Photosensitive polyimides (PIs) as an alignment layer induced optical switc hing of nematic liquid crystal (NLC) on photoirradiation at 366 nm. The ori entation of NLC molecule was changed from homogeneous to homeotropic alignm ent on photoirradiation with a dc electric field as a bias. The optical swi tching behavior of NLC was largely affected by the chemical structures of P Is. (C) 1999 American Institute of Physics. [S0003-6951(99)02748-5].
