Molecular-Oriented Photoalignment Layer for Liquid Crystals
In this letter, we describe the fabrication of a durable photoalignment layer for liquid crystals (LC) with high azimuthal anchoring and controllability of the tilt angle. A film is irradiated using linearly polarized ultraviolet (LPUV) light followed by annealing which induces the molecular orientation of the photoalignment layer. The nematic LC was aligned parallel to the electric vector of the LPUV light, and the alignment layer showed high thermal stability of the orientational characteristics up to 250 °C.
