Mask for color cathode ray tube having beneficial slot and bridge configurations, manufacturing method thereof, and exposure mask for manufacturing the mask |
摘要 |
A mask for a color cathode ray tube (CRT) and a manufacturing method thereof are provided. This mask includes a plurality of strips isolated from each other at predetermined intervals in parallel, and a plurality of bridges for forming slots through which electron beams pass by connecting adjacent strips to each other. In this mask, each of the bridges between adjacent strips has a first curved portion formed on the side from which electron beams come out, and a second curved portion formed on the side upon which electron beams are incident. The first curved portion has a first width in the direction perpendicular to the length direction of the strips, and extends in the length direction of the strips. The second curved portion has a second width that is smaller than the first width in the length direction of the adjacent strips.
