N2 - Generation of pretilt angles in a nematic liquid crystal (NLC) using an in situ photoalignment method with polarized UV exposure during imidization of polyimide (PI) on two kinds of PI surfaces with side chains was investigated. The pretilt angles of NLC generated using the in situ photoalignment method were smaller than those generated using a conventional photoalignment method for a short UV exposure time. Also, the pretilt angles of NLC generated using the in situ photoalignment method increase with increasing UV exposure time on PI surfaces. Finally, the pretilt angles of NLC can be improved by annealing.
