Popis:	We report the use of graphene as a highly transparent conductive film in liquid-crystal displays (LCDs). Graphene films were synthesised via chemical vapour deposition, transferred onto glass substrates, and then used to fabricate typical twisted nematic LCD cells. LCD cells using graphene as transparent electrodes exhibited optical transmittances 7.7% higher than LCD cells fabricated using conventional conducting layers based on indium tin oxide (ITO) films. The device characteristics of LCD cells based on graphene electrodes, such as threshold voltage and voltage holding ratio, were comparable to those of conventional LCD cells based on ITO electrodes. These results indicate that graphene is a promising transparent conductive film compared to ITO, yielding LCDs with significantly improved optical transmittance.
