The new generation Liquid-Crystal Displays(LCDs) will play a key role in modern display indus-try thus the requirements concerning the response time,power consumption, viewing angles, contrast ratio andeasy production stay beyond challenging. In this paper wedemonstrate fabrication of large scale liquid crystal devicewith graphene-based electrodes using a photo-alignmenttechnique. The quality of graphene layer, grown by lowpressure CVD method and transferred on the glass sub-strates was characterized by several techniques: Ramanspectroscopy, optical transmittance and electrical mea-surements. A photo-alignment method instead of com-monly used mechanical rubbing technique was used toprotect the graphene surface and prevent its partial de-attachment from the glass substrates by coating a poly-imide layer on the top of graphene. Measured modulationcharacteristics reveal that the photo-alignment techniquepossesses great potential for next generation graphene -based LC device fabrication.
