Info: (Extract from WIKIPEDIA):
A Liquid Crystal Display (LCD) is a flat panel display, electronic visual display, or video display that uses the light modulating properties of liquid crystals.
Liquid crystals do not emit light directly.
LCDs are used in a wide range of applications including computer monitors, televisions, instrument panels, aircraft cockpit displays, and signage.
They are common in consumer devices such as DVD players, gaming devices, clocks, watches, calculators
Since they do not use phosphors, they do not suffer image burn-in.
Its low electrical power consumption enables it to be used in battery-powered electronic equipment.
It is an electronically modulated optical device made up of any number of segments filled with liquid crystals and arrayed in front of a light source (backlight)
or reflector to produce images in color or monochrome.
Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes,
and two polarizing filters (parallel and perpendicular), the axes of transmission of which are (in most of the cases) perpendicular to each other.
Without the liquid crystal between the polarizing filters, light passing through the first filter would be blocked by the second (crossed) polarizer.
