GLASS SPACER FOR ELECTRON-EXCITING DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a glass spacer for an electron-beam-exciting display capable of improving a surface strength by an efficient rapid cooling at heating and drawing of a mother material glass. SOLUTION: The flat electron-beam-exciting display is provided with a front face plate 1 made of a glass substrate 15 with an image forming member 5 formed on the inside face and a back face plate 2 made of a glass substrate 21 loading an electron emission element group. The image forming member 5 is provided with a phosphor emitting light by electron beams irradiated from an electron emission element. The front face plate 1 and the back face plate 2 are bonded together airtight through a supporting frame 3 to form a vacuum vessel making up an airtight anti-atmospheric pressure structure together with the supporting frame 3, with a plurality of glass spacers 4 as atmospheric pressure supporting members inserted between the front face plate 1 and the back face plate 2. The glass spacer 4 has a side length of its cross-section shape longer than a height of the same and a side face in either a circular arc concave or convex face. COPYRIGHT: (C)2004,JPO
