Abstract
A composition of a getter and a field emission display (FED) using the same are disclosed which are capable of improving a degree of vacuum and a gas rejection capability by performing an activation process by using a getter that can lower an activation temperature. The composition of the getter comprises chrome and the field emission display contains the getter having chrome as a main component.

A composition of a getter comprising:
- 20 atomic %˜70 atomic % chromium (Cr);
- titanium (Ti), wherein the Ti is ≦30 atomic %;
- and
- 20 atomic %˜50 atomic % zirconium (Zr).
A field emission display (FED) comprising a getter having a composition ratio of 20 atomic % to 70 atomic % Cr, Ti, and 20 atomic % to 50 atomic % Zr, wherein the Ti is ≦30 atomic %.
A getter for a field emission display (FED) comprising:
- 20 to 70 atomic % Cr;
- 20 to 50 atomic % Zr;
- and
- 0 to 30 atomic % Ti wherein said Ti is greater than 0 atomic %.
