Title: Image display device
Inventor: ONO KATSUTOSHI
IPC: H01J31/12
Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To aim at thickness reduction of an image display device by providing a vacuum holding part for setting the inside of a space formed by a front panel, a rear panel and a jointing member in a vacuum state and providing a image display part in the abovementioned space. SOLUTION: In order to maintain the inside of a vacuum holding part 2 to vacuum, the atmospheric pressure is applied in an arrow mark A1 direction to generate a stress as warping the front panel 4 and the rear panel 5 inward. However, planar glass comparatively thick and having sufficient strength and rigidity is used for both panels, they are not supposed to warp so that the vacuum state can be securely maintained. Meanwhile, since planar glass used in the fluorescent part of a image display part 3 is only for the purpose of holding a fluorescent surface not for holding the vacuum state, comparatively thin material can be used.  Therefore, since the front panel 4 and the rear panel 5 are in planar shapes, the thickness of the entire device can be remarkably reduced in comparison with such a structure as being given radius of curvature to those members for holding the conventional vacuum state.
