Abstract:
A cathode ray tube comprising:an electron gun for emitting an electron beam for scanning; a panel disposed so that a back side of the panel faces the electron gun; a color selecting member formed of a single layer and disposed between the back side of the panel and the electron gun and having a slit elongated in a same direction as a longitudinal direction of a shape of the panel, thereby allowing the electron beam for scanning to pass through the slit; and a phosphor layer provided on the back side of the panel and having a pattern in stripes corresponding to a shape of the slit in the color selecting member so as to be irradiated with the electron beam passed through the slit in the color selecting member, wherein the electron beam passes through the slit last before irradiating the phosphor layer, wherein a plurality of electron guns are arranged linearly in the longitudinal direction of the shape of the panel.
