Nematic refers to a state of matter found in certain liquid crystals, where the molecules are oriented in parallel but not arranged in a fixed position. This unique alignment allows nematic liquid crystals to flow like a liquid while maintaining some degree of order, making them useful in various applications, particularly in display technologies. In electronics, nematic liquid crystals are commonly used in LCD (Liquid Crystal Display) screens. Their ability to manipulate light when an electric field is applied enables the creation of images on devices like televisions, computer monitors, and smartphones.
