A low turn-on voltage of polymer light-emitting diode, PLED is important for economical display application. We had fabricated the nanoparticlesTiO2 thin film between ITO and PDPV in Al/PDPV/ITO structure as a hole injection layer. The sol gel method synthesized of TiO2 thin film was deposited using spin coating technique. It was found that TiO2 has reduced the turn-on voltage of the original PLED device from 8.0 V to 5.0 V.
