PROBLEM TO BE SOLVED: To provide a vacuum vessel capable of suppressing a crack of a spacer due to an impact applied to the spacer during an exhausting process, and to provide an electron emission display device using this. SOLUTION: The vacuum vessel 100 of this invention includes a first substrate 2 and a second substrate 4 arranged facing each other and having an effective area 30 which is an area wherein emission or image display is performed and an un-effective area 32 arranged along the border of the effective area 30, a sealing member 6 disposed to the circumference of the facing area of the first substrate 2 and the first second substrate 4, a wall type spacer 34 provided crossing the effective area 30 between the first substrate 2 and the first second substrate, and a spacer supporting body 36 provided in the un-effective area 32 between the first substrate 2 and the first second substrate 4, having a groove part 38 in which an end part of each spacer 34 is inserted and having height larger than height of the spacer 34. Thereby, the crack of the spacer 34 due to the impact applied to the spacer 34 in the exhausting process can be prevented. COPYRIGHT: (C)2007,JPO&INPIT
