Many of the electronic devices we use in our daily life rely on liquid crystal display (LCD) technologies. LCDs get their name from the special liquid crystal solution that is contained between two thin glass plates inside the display. An electric field applied across the liquid crystal layer changes optical properties of the liquid crystals thus enabling their use in displays. A new paper reports several interesting size effects including monotonous and non-monotonous dependence of the total concentration of mobile ions in liquid crystals on the thickness of the cell and/or on the concentration of nanoparticles.
