摘要：<p>PROBLEM TO BE SOLVED: To provide a high quality image where aging deterioration of bright ness is reduced and beam drift is reduced, by providing a getter material on a wiring for transmitting a driving signal to an electron emission element. SOLUTION: After a column-directional wiring and an insulating layer are formed and a row-directional wiring 1013 is formed by coating an Ag paste with a screen printing, a non-evaporative getter is put on it by reduced-pressure plasma spraying under low-pressure argon atmosphere to provide a getter 101. A forming region of the getter 101 is smaller than that equivalent to a spacer 1020 width to prevent electron track deflection caused by extrusion from the wiring. Using a conductive connection member 1040 where matters formed by metal-plating spherical-glass-made insulating feelers are dispersed in flit glass, a face plate 1017 and a face-plate-side-spacer electrode 1020c are electrically interconnected, and a spacer 1020 is fixed, and then they are assembled and arranged using 2 mm as an interval (d) between an electron source substrate 1011 and the face plate 1017. Thus, an image that has no color drift, high quality, and high brightness is provided stably for a long time.</p>
