On a back surface of a back substrate on which electron emission sources
are formed, a getter room is formed by the back substrate and a
cup-shaped room member. In the inside of the getter room, a getter
assembly which includes a getter housing which holds a getter and a
getter support which supports the getter housing is arranged. End
portions of the getter support are fixed to and arranged between the back
substrate and the room member by a sealing material. The present
invention provides an image display device which prevents the occurrence
of cracks in the getter room thus suppressing the degradation of a
display characteristic of the image display device.
