Cathode-ray tube and method of manufacturing the same

摘要

A vacuum envelope of a cathode-ray tube includes a panel and a funnel section opposed to the panel. The funnel section has two funnels each having a cone section. Each of the funnels is formed by cutting one side portion of a base funnel which is formed by pressing. The two funnels are joined together at sections thereof so as to form the funnel section and also joined to the panel into the vacuum envelope. A neck containing an electron gun is joined to each of the cone sections. A phosphor screen formed on the inner surface has two scanning regions which are divided scanned by electron beams emitted from the electron guns.
