Abstract (en)
[origin: EP0818800A1] A shadow mask opposing a phosphor screen includes a substantially rectangular mask body (27) having a number of electron beam passage holes, and a substantially rectangular mask frame (30) having four side walls (28L, 28S) supporting a periphery of the mask body. Among the side walls, a pair of the side walls (28L) on long side each has a central connecting portion (32a) which is provided in a central portion thereof in lengthwise direction and fixed to the mask body, and a pair of protruding portions (34) which are provided on both sides of the central connecting portion in the lengthwise direction and protrudes in a direction apart from the mask body. Each protruding portion defines a gap (36) between the side wall and the mask body, and a width of the gap gradually increases as it goes far from the central connecting portion. <IMAGE>
