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.
Claims16
An image display device including a vacuum envelope in which a back substrate which forms electron emission sources thereon and a face substrate which forms an anode and phosphor layers thereon are arranged to face each other, wherein a room member for forming a getter room which is communicated with the vacuum envelope is bonded to a back surface of the back substrate by way of a sealing material,
- a getter assembly is arranged in the inside of a getter room, the getter assembly includes a getter material, a getter housing which holds the getter material, and a getter support,
- the getter housing is arranged in the inside of the getter room in a state that the getter housing is supported on the getter support, and
- the getter support is fixed between the back substrate and the room member by way of the sealing material.
An image display device including a vacuum envelope in which a back substrate which forms electron emission sources thereon and a face substrate which forms an anode and phosphors thereon are arranged to face each other in an opposed manner, wherein
- a getter room which is communicated with the vacuum envelope is formed on a back surface of the back substrate, the getter room is constituted of a room member, a getter assembly is arranged in the inside of the getter room, and the getter assembly includes a getter, a getter housing which holds the getter, a getter support which supports the getter housing and a positioning rod which sets an arrangement position of the getter, wherein
- the room member includes a positioning groove in which a distal end portion of the positioning rod is inserted, and the distal end portion of the positioning rod is inserted into the inside of the positioning groove.
