Abstract
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, in which phosphor layer has a pattern in stripes in the lateral direction of a screen, or in the horizontal direction and 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 actual 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.
