Is mercury a liquid crystal?
Mercury, Hg, is NOT a liquid crystal. It’s a liquid at some temperatures, and a crystal at other temperatures, but it is never a liquid crystal.
Why do monitors contain mercury?
Compact fluorescent lamps and fluorescent tubes (including cold-cathode fluorescent tubes used for backlighting LCD TV and monitor screens) contain small quantities of mercury. Light is generated by gas discharge and the excitation of mercury vapour, which causes a plasma to be formed.
