Apparatus for removing impure gases from gas discharge display apparatus

Abstract

An apparatus for removing impure gases from a gas discharge display apparatus is disclosed, which includes a getter engaged at an outer portion of an image effective portion of the vacuum space for absorbing an impure gas, and a blocking wall for preventing the getter from being scattered toward the image effective portion in a gas discharge display apparatus in which a certain space is formed between a pair of substrates, and the substrates are sealed by a sealant, and a combined gas which is used for an electrode discharge is filled into a vacuum space formed between the substrates after an impure gas is exhausted therefrom by a ventilation/vacuum process, for thereby enhancing an image characteristic by preventing a getter material from being scattered toward an image display surface.
