In this article, we proposed a new technique for the improvement of contrast ratio (CR) of the (BaTiO 3 ) nanoparticle doped polymer dispersed liquid crystals (Np PDLC) display. For the purpose, an extra polymer layer has been employed at the lowermost part of the nanoparticle doped PDLC film. By adopting such technique, we found significantly improved electro optical contrast of Np PDLC film. The contrast ratio of the Np doped PDLC device fabricated with extra polymer layer (PDLC C) offered 7.24, which was found as the best among all the fabricated devices. The results o f the study have been verified by experimental techniques. Such technique has been found easy to employ and could be used for attaining better Np PDLC display. All the results have been discussed in detail. The current Np doped PDLC methodology could be us eful for various display applications..
