We present unique optical effects in nanoparticle (NP)-embedded liquid crystal devices. For conducting this research, we synthesized PgCyD-ZrO₂ and we prepared NP system comprised of seven NPs of Aerosil R-812 (EVONIK) through a sonication, where the original Aerosil has the size of 400 nm. LCD device cells embedded with these NPs exhibit the optical enhancement effects such as reduction of laser speckle patterns, increase of output intensity, viewing angle, and color gamut and further reduction of power consumption evaluated through luminance efficiency. This chapter is written by updating the previous publications [1-8] through describing the details of syntheses of NP and giving physical modeling of light scattering based on Rayleigh-Gans scattering theory accompanying an updated figure and also the effect of raising effective temperature called Kobayashi temperature and pretilt increasing effect with simulation.
