Vacuum envelope and electron emission display using vacuum envelope

摘要

A vacuum envelope and an electron emission display having the vacuum envelope are provided. The vacuum envelope includes a first substrate (2) and a second substrate (4) facing the first substrate. A side member (6) is disposed at peripheries of the first substrate and the second substrate. A first spacer (81) is disposed between the first substrate and the second substrate at an active area (A) of the vacuum envelope, and a second spacer (82) is disposed between the first substrate and the second substrate at a non-active area (NA) of the vacuum envelope, the non-active area surrounding the active area. A height (H1) of the first spacer is greater than a height (H2) of the second spacer.
