PROBLEM TO BE SOLVED: To provide an electron emission display device in which sealing process can be carried out easily using an upper barrier rib and a lower barrier rib as an alternative method to the loading process of a spacer, and its manufacturing method. SOLUTION: The electron emission display device comprises a cathode substrate having one or more electron emitting elements, a lower barrier rib formed selectively in the prescribed region on the cathode substrate, an anode substrate having an image realizing region corresponding to the electron emitting elements, and an upper barrier rib formed selectively on the anode substrate opposed to the cathode substrate. The cathode substrate and the anode substrate are supported by the lower barrier rib and the upper barrier rib, and the lower barrier rib and the upper barrier rib contain foam glass. By using the barrier ribs made of foamd glass, abnormal emission of light of the spacer and electron buildup phenomenon to the spacer can be prevented. Furthermore, since this has no loading process of the spacer, yield of manufacturing can be improved. COPYRIGHT: (C)2006,JPO&NCIPI
