ABSTRACT:
In order to prevent a spacer from being charged by using a plate shaped spacer covered with a high resistance film, the present invention is aimed at preventing irregular displacements of electron beams emitted from adjacent electron-emitting devices and suppressing displacements of impinging positions of the electron beams emitted from the adjacent electron-emitting devices even with a slight displacement of an installation position of the spacer. The spacer is disposed along a row directional wiring. The high resistance film is allowed to come into contact with a metal back and the row directional wiring to achieve electrical connection therebetween. Contact portions between the high resistance film of the spacer and the row directional wiring are provided at predetermined intervals.
