Abstract
A vacuum envelope and an electron emission display having the vacuum envelope. The vacuum envelope includes a first substrate and a second substrate facing the first substrate. A plurality of frames is arranged between the first substrate and the second substrate to form an inner vacuum space. An absorbing member is arranged between at least two of the frames.

A vacuum envelope, comprising:
- a first substrate;
- a second substrate facing the first substrate;
- a plurality of frames arranged between the first substrate and the second substrate to form an inner vacuum space, the frames comprising a first lateral frame and a first longitudinal frame;
- and
- an absorbing member arranged between the first lateral frame and the first longitudinal frame, the absorbing member connecting to the first longitudinal frame at a right angle with respect to the first substrate, and connecting to the first lateral frame at a right angle with respect to the first substrate.
