摘要： A mask assembly for a Cathode Ray Tube (CRT) includes a shadow mask with a plurality of beam passage holes, and a frame including a supporting portion with a pair of long sides and a pair of short sides which fix the shadow mask and a strength maintenance portion bent from the supporting portion. The frame includes a plurality of reinforcement indentations formed on a portion of the boundary between the supporting portion and the strength maintenance portion. At least one of the reinforcement indentations satisfies the following condition: S 1 3 ≤ S 2 ≤ 2 3 ⁢ S 1 wherein S1 represents an area of a triangle defined by a width of the supporting portion including the reinforcement indentation, a width of the strength maintenance portion including the reinforcement indentation and an imaginary line connecting an end of the supporting portion and an end of the strength maintenance portion, and wherein S2 represents a sectional area of the reinforcement indentation.
