Abstract

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.(FIG. 3A)
