Abstract
The present invention, to realize a compact projection-type television receiver set, provides a flattened projection-type cathode ray tube of a projection-type television receiver set. The projection-type cathode ray tube includes a phosphor screen panel, a phosphor screen formed on an inner surface of the phosphor screen panel, a face panel which is arranged to face the phosphor screen in an opposed manner, and an electron gun for forming an image on the phosphor screen, wherein the phosphor screen is inclined with respect to a tube axis on which the electron gun is arranged.
Claims7
A projection-type cathode ray tube comprising a vacuum envelope formed of a panel portion, a neck portion having an electron gun which irradiates electron beams, and a funnel portion which connects the panel portion and the neck portion, wherein
- the panel portion including a phosphor screen panel which includes a phosphor screen on an inner surface thereof, and a face panel which is arranged to face the phosphor screen of the phosphor screen panel,
- a center axis of the phosphor screen is inclined with respect to a tube axis along which the electron gun is arranged, and
- the emitted light on the phosphor screen is projected to the outside of the vacuum envelope after passing through the face panel.
