Abstract
An image display device is constituted such that a back substrate on which image signal lines, scanning signal lines and electron sources are arranged and a face substrate which has phosphor layers are hermetically sealed to each other by way of a frame body using a sealing material, and the inside of the image display device is formed into a vacuum. A length LSK of a second sealing region into which scanning signal lines hermetically penetrate is set larger than a length LDK of a first sealing region into which thin-film image signal lines hermetically penetrate and hence, it is possible to suppress the decrease of the degree of vacuum.
Claims11
An image display device comprising:
- a back substrate which includes a plurality of first lines which extend in the first direction and are arranged in parallel in the second direction which intersects the first direction, an insulation film which is formed in a state that the insulation film covers the first lines, a plurality of second lines which extend in the second direction and are arranged in parallel in the first direction, and electron sources which are connected to the first lines and the second lines;
- a face substrate which includes phosphor layers of a plurality of colors which emit light due to excitation thereof by electrons emitted from the electron sources and an anode, the face substrate facing the back substrate with a predetermined distance therebetween;
- a frame body which surrounds a display region between the back substrate and the face substrate and holds the predetermined distance;
- a panel which includes a sealing material which hermetically seals end surfaces of the frame body to the face substrate and the back substrate respectively and evacuate air in a space surrounded by the back substrate, the face substrate and the frame body, wherein
- the image display device includes a first sealing region in which a sealing material which extends in the second direction is arranged on the plurality of first lines and a second region in which a sealing material which extends in the first direction is arranged on the plurality of second lines, and
- a first-direction width of the first sealing region and a second-direction width of the second sealing region differ from each other.
