What is Nematic Liquid Crystal?
Nematic liquid crystal is a translucent liquid that changes the polarity of light waves passing through it. The word “nematic” comes from the Greek word for thread, and describes the thread-like formations that can form in the liquid crystal. Nematic liquid crystal is frequently used in liquid-crystal displays (LCD) screens such as those on digital watches. Liquid crystals are an intermediate melting stage between a solid state and a liquid state. In 1888, an Austrian scientist named Freidrich Reinitzer discovered the state as he conducted experiments on a substance called cholesterol benzoate. The substance, Reinitzer noticed, had two distinct melting points. In the first it became a cloudy liquid, and in the second it became transparent. Reinitzer’s observations included the concepts that the cloudy or crystalline state changed the polarity of light waves passing through it, a concept imperative to the development of LCD. Reinitzer never developed practical applications of liquid cry
