A cathode ray tube and a color selecting member, which can be manufactured without defects by using an existing projection aligner of a simple structure and can always produce a picture of high quality, and manufacture methods thereof. A phosphor layer has a pattern in stripes in the lateral direction of a screen, or in the horizontal direction. A color selecting member has slits elongated in the longitudinal direction of the screen, or in the horizontal scan line direction. Even in case of the thermal expansion of the color selecting member or a considerable longitudinal deviation between the exposure position at the time of manufacture and the position where an electron beam strikes in practical use, an electron beam can freely pass through the slits. Therefore, the accuracy of irradiation of the phosphor layer with the electron beam is not adversely influenced.
A cathode ray tube comprising:
A method of manufacturing a cathode ray tube, comprising steps of:
A color selecting member incorporated and used in a cathode ray tube comprising an electron gun, a panel and a phosphor layer disposed on a back side of the panel, the color selecting member having a slit for allowing an electron beam emitted from the electron gun to pass through and move toward the phosphor layer,
A method of manufacturing a color selecting member incorporated and used in a cathode ray tube comprising an electron gun, a panel on which a picture is produced, and a phosphor layer disposed on a back side of the panel, the color selecting member having a slit for allowing an electron beam emitted from the electron gun to pass through and move toward the phosphor layer, the method comprising steps of:
