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.
