Abstract
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.
