Abstract

We have fabricated twisted nematic (TN) liquid crystal cells doped by carbon nanotubes (CNTs) with different CNT wt.%. With a minute amount doping, multi-walled CNTs did not perturb the liquid crystal orientations in the off- and on-state. The hysteresis studies of voltage-dependent transmittance (V-T) and capacitance (V-C) under the influence of electric field generated by ac and dc voltage show that the amount of residual dc, which is related to image sticking problem in liquid crystal displays, is greatly reduced due to ion trapping by CNTs. Also, the V-T and V-C hysteresis is dependent on concentration of multi-walled CNTs.
