Cathode ray tube |
摘要 |
An inner magnetic shield is provided that reduces mislanding lengths due to electron beam distortion caused by external magnetic fields such as terrestrial magnetism, thereby reducing the occurrence of drifted or uneven color throughout an entire display screen. The inner magnetic shield is of a tube with a plurality of side surfaces, and is provided with at least one skirt (37) that extends to the vicinity of a spanning member (41) at a location where the inner magnetic shield is not in contact with a holding member (42). The skirt (37) is magnetically coupled with the spanning member (42).
