In the last three decades, sufficient research has been conducted by the various research groups on the electro-optical and dielectric properties of liquid crystals (LCs) in homogeneously and vertically aligned liquid crystal (LC) systems. The current knowledge in the given research field is described, and the majority of the research is focused on dispersed LC systems using different types of nanoscale particles such as nanoparticles (NPs), quantum dots (QDs), and nanorods (NRs) to study their effect on the electro-optical, dielectric, and conductivity performances of homogeneous and vertical LC cells. The existing research stated the role of various types of metal and metal oxide (Au, Ag, Pt, Si, TiO2, NiO, Fe2O3, diamond, etc.) NPs dispersed in nematic LCs. Thus, NPs dispersed LC composites have gained thought-provoking scientific and technological interest, mainly because the incorporation of NPs enhances the electro-optical and dielectric properties of the LCs. In addition, there is the wide scope of research work to study the detailed dielectric behaviour of the vertically aligned LCs induced using contact (polyimide coated substrates) and non-contact (self-assembled NPs deposited substrates) methods with the negative dielectric anisotropy LCs. Thus, the proposed work will be mapped with a suitable combination of LC, nanomaterials, LC orientations, and cell configurations to obtain a superior performance from LC-based display devices. The purpose of this research is to develop energy-efficient, high-contrast flexible LC displays using a non-contact method. Specifically, the performance characteristics of vertically aligned nematic LCs of negative dielectric anisotropy using nanoscale particles of varied sizes and concentrations will be controlled, and electro-optical as well as dielectric behaviour will be studied.
