Alignment of liquid crystals (LC) sandwiched between ion‐beam (IB)‐spurted graphene‐oxide (GO) thin layers is presented in this manuscript. LC alignment is found sensitive to the direction and acceleration energy of spurted IB, and IB accelerated with a 45° incident angle is the most suitable and effective to align LC at the lowest acceleration energy. Generated Chemical radicals on GO thin layers during IB spurting process are responsible for the alignment of LC, which were also confirmed by the chemical information variation in XPS spectra. The increased LC anchoring on GO thin layers generated by spurted IB was also confirmed by the measured anchoring energies of LC on GO thin layers. LC sandwiched between IB‐spurted GO thin layers also present competitive switching performances.
