Explanation:
Detailed explanation-1: -A liquid crystal display (LCD) has liquid crystal material sandwiched between two sheets of glass. Without any voltage applied between transparent electrodes, liquid crystal molecules are aligned in parallel with the glass surface.
Detailed explanation-2: -LCDs use these liquid crystals because they react predictably to electric current in such a way as to control light passage. Most liquid crystal molecules are rod-shaped and are broadly categorized as either thermotropic or lyotropic.
