- Abbreviation of liquid crystal display. A display incorporating liquid crystals sandwiched between glass plates which have a transparent conductive coating, or electrodes, which serve to vary the electric field surrounding said crystals, thus changing their optical properties. LCDs can be reflective or transmissive, and are used in a variety of flat display devices, such as those of portable computers, calculators, or watches. Improved viewing characteristics may be seen, for instance, in active matrix displays and nematic-crystal displays. Also called LCD display (1).
