摘要： PURPOSE:To make the whole surface of a phosphor screen seamless by dividing a shadow mask in the horizontal direction, and constituting the shielding parts of the space parts out of a shielding body having an opening hole and an opening hole shielding body. CONSTITUTION:A shadow mask 18 is divided in the horizontal direction, and is formed as divided masks M1 to M5. The shielding parts 25 of the space parts of the masks M1 to M5 are constituted of the first shielding body 27 having an opening hole 26 through which a support body 21 passes penetratingly with allowance and the second shielding body 28 to cut off the opening hole 26. At this time, electron beams deflected and scanned by crossing areas R1 to R20 of a phosphor screen 18 are shielded completely by the noneffective parts of the masks M1 to M5, the first shielding body 27 and the second shielding body 28 to cut off the opening hole 26, and undesired phosphor emitting light by incidence of an overly scanning electron beam is prevented. A seamless excellent grade image is obtained over the whole surface of the screen 17.
