Claim:
A tension mask frame assembly of a color CRT, comprising: a tension mask perforated by a plurality of electron beam passing holes; and a frame, comprising: first and second support members separated a first predetermined distance from each other and supporting the tension mask so that a tensile force is applied to the tension mask; first and second elastic members installed between both end portions of each of the first and second support members and supporting the first and second support members to be separated said first predetermined distance from each other to compensate for an amount of thermal expansion of the tension mask; and a pair of bars connecting the first and second support members, said pair of bars and said first and said second support members forming essentially a closed rectangle that forms a periphery for said tension mask, said pair of bars, said tension mask and said first and second support members all being disposed in essentially a single plane, said first and said second elastic members having inclined portions that form acute angles with a corresponding support bar, said elastic members not being disposed in the same plane defined by the tension mask, the bars and the elastic support members.
