Abstract:
An enclosure having a front substrate (11) provided with a display surface and a rear substrate disposed opposite to the front substrate is provided. The front substrate has a metal back (20) formed by being overlapped on the display surface and getter film (22) formed of at least two types of active metal on the metal back. The getter film is formed by depositing a plurality of getter materials. The invention can improve the gas adsorption characteristics of a getter film to characteristics obtained by combining a plurality of getter materials. Accordingly, an image display unit capable of providing a broader design range of getter film characteristics, maintaining a high vacuum degree inside an enclosure, and keeping high display performance over an extended period; and a production method therefore can be obtained.
Abstract:
A field emission display comprises a front plate having many phosphor layers and a back plate having many electron emitters, and the peripheral portions of these plates are bonded together and the inside thereof is evacuated. A non-evaporable getter member (22) for adsorbing a gas is formed on the surface of a metal back (20) of a phosphor screen which is provided on the inner surface of the front plate. The non-evaporable getter member (22) is composed of a fine powder (22a) of a non-evaporable getter and an inorganic binder (22b), and has a network structure by drying and fixing the inorganic binder (22b).
