Abstract

The present invention relates to a LCD (Liquid Crystal Display) getter in which can make possible to handle a high vacuum level by absorbing remaining gases inside of a closed container with chemical reaction in first vacuum handled by vacuum pump, especially which can make to use exclusively in CCFL (Cold Cathode Fluorescent Lamp) of TFT-LCD (Thin Film Transistor - Liquid Crystal Display) including mercury with structural element of the getter. Also, the getter of the present invention can make not only to handle FFL (Flat Fluorescent Lamp) in a surface back lighting method of TFT-LCD and a high vacuum level including a certain amount of mercury, but also a kind of a inert gas lamp including very small amount of mercury.
