Before we discuss about liquid crystal display we know hiwhat is liquid crystal. A state of mater which is district state between the crystalline (solid) and isotropic (liquid) having ordering properties of solids but how like liquids. The property of liquid crystal exhibiting the properties of both solids and liquids in applied in the producing liquid crystal display. Since liquid crystal could not emit light directly, the light modulating character of liquid crystal is used in manufacturing a liquid crystal display which a flat panel display and also termed as electronic virtual display or video display. LCD’s can be used to show random images like In a computer display or fixed images which can be shown or concealed like prefix work as in a digital clock. Basic technology is used is some, except random images are constituted with a large no small pixels. While larger elements are used in other displays. The LCD technology helped in creating thin & energy efficient devices as compared with CRT devices. The LCD devices can be disposed more safely as compared with CRT. LCD being a better device than CRT. CRT is discarded for the most of the purpose. Hence we see that 5 X 7 nature display, digital display board & CD
