Abstract: A display device includes a front substrate having an anode and fluorescent materials on an inner surface, and a back substrate having a plurality of cathode lines and include electron sources, and a plurality of control electrodes allow electrons from the electron sources to emit to the front substrate side, on an inner surface thereof. The back substrate is arranged to face the front substrate in an opposed manner with a given gap therebetween, and an outer frame for holding the given gap is interposed between the front substrate and the back substrate and extends around the display region. An inner frame is arranged outside the display region and inside the outer frame, and a getter is provided between the outer frame and the inner frame.

Abstract: Inside an outer frame, which is interposed at between opposedly facing peripheries between a back substrate and a front substrate, there is an inner frame which fixes both end portions of plate member control electrodes, which are constituted of a large number of parallel strip-like electrode elements. By integrally forming the plate member control electrodes such that the plate member control electrodes are fixed to both end portions of a display region, a single part is formed. Further, a getter chamber is formed between the outer frame and the inner frame and getters are accommodated in the getter chamber. Due to such a constitution, the operability and yield rate of products at the time of assembling can be enhanced. Further, it is possible to hold a desired degree of vacuum in the space between the substrates for a long time.
