Patent ID: 7348721

Claim:
A display device comprising: a face substrate having anodes and phosphors formed on an inner surface thereof; a plurality of cathode lines which extend in a first direction and are arranged in parallel in a second direction which crosses the first direction and include electron sources; control electrodes which cross the cathode lines in a display region in a non-contact manner and have electron passing apertures for allowing electrodes from the electron sources to pass through the control electrodes to the face substrate side; a back substrate on which the control electrodes and the cathode lines are formed on an inner surface thereof and face the face substrate in an opposed manner with a given distance therebetween; a support body which is interposed between the face substrate and the back substrate in a state that the support body surrounds the display region and holds the given distance; a sealing material which hermetically seals end faces of the support body and the face substrate and the back substrate respectively; and a plurality of getters; wherein: the getters include a getter material, a getter vessel housing the getter material and a getter support supporting the getter vessel; a partition wall body which extends parallel to the support body and is arranged from the support body internally and outside the display region and is fixed to the back substrate; a gap is present between the partition wall body and the face substrate; each getter is arranged between the support body and the partition wall body.
