A form of visual display used in electronic devices in which a layer of a liquid crystal is sandwiched between two transparent electrodes. The application of an electric current to a small area of the layer alters the alignment of its molecules, which affects its reflectivity or its transmission of polarized light and makes it opaque.
- The thin film transistors are useful in active matrix liquid crystal displays where the plastic substrates are transparent in the visible spectrum.
- The cockpit is equipped with multifunction liquid crystal displays and electronic flight instruments.
- But many laptop computers have liquid crystal displays (LCDs).
