A shadow mask assembly is formed such that a corner spring is attached to the side wall of a frame supporting a shadow mask. The corner spring has a supporting plate wherein a hole, into which a stud pin penetrates is formed at tile center; a pair of wings which extend in the direction of both sides of the supporting plate; and a welding plate which is formed by bending the supporting plate in a U-shape perpendicular to both wings. Minute space being formed between both wings and the side walls of the frame corresponding to the wings and facing and parallel to each other, and slots are inclined at an angle agreeing with a deflecting angle .beta. of an electron beam. Projections are combined with the slots, so that displacement by a thermal expansion of the frame is guided according to the deflecting angle.
