We report the electro-optic (EO) characteristics of a Y 2O 3 nanoparticle-doped nematic liquid crystal (NLC) system. After doping with 2wt.% Y 2O 3 nanoparticles, LC alignment shows a homogeneous orientation state without aggregation and crack. In particular, the pretilt angle was slightly increased in proportion to Y 2O 3 doping concentration. Response time was improved by nearly 53%, and the threshold voltage for display operation was reduced from 4.2V to 2.6V. We assumed that superior EO properties were achieved by the Y 2O 3 nanoparticle, which reduces the field-screening effect of impurity ions. We also confirmed that enhanced EO characteristics were achieved without loss of light transmittance.
