| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a cathode-ray tube having a color discriminating mechanism capable of bringing a vibration isolating wire laid on an aperture grill into contact with all AG tapes. SOLUTION: This cathode-ray tube is provided with a color discriminating mechanism comprising a frame and an aperture grill 5 having a plurality of lines of slit holes 4 for selectively transmitting electron beams which is laid over the frame. A slit groove 11 capable of shielding light is provided on an endmost metal thin plate part 7 on the outside of the slit hole 4 situated on the endmost side of the slit holes 4, whereby the rigidity of the endmost metal thin plate part 7 is reduced. |
