Abstract: In a cathode ray tube including a panel provided with a phosphor screen, a funnel integrated with the panel, an electron gun disposed inside the funnel, a magnetic shield (1) for shielding an electron beam (5) emitted from the electron gun against an external magnetic field, and a frame (2) for holding the magnetic shield (1), the magnetic shield (1) includes, at a portion to be joined with the frame (2), a bent portion (20) bent toward a tube axis side, and a thickness T of the bent portion (20) at its edge on the tube axis side is 0.08 mm or less. By making the thickness T small, halation that is liable to occur in a cathode ray tube with a large deflection angle can be suppressed because electron beams reflected from an end face (11) and allowed to reach the screen without being shielded by the frame (2) are reduced.

Abstract: The phosphor screen is capable of minimizing the spread of lights in the phosphor screen, so as to restrict fading images and lowering contrast. The phosphor screen comprises a lot of minute phosphor sections. The phosphor sections are respectively enclosed by barriers, which absorb visible lights and have electric conductance, and whose height is equal to or higher than a half of thickness of the phosphor sections. The barriers are made of a material including the particles of an inorganic compound, whose average diameter is 1-8 &mgr;m, and carbon particles, whose average diameter is less than 1 &mgr;m.

Abstract: A method of manufacturing a luminescent screen assembly for a cathode ray tube (CRT) is disclosed. The luminescent screen assembly is formed on an interior surface of a faceplate panel of the CRT. The luminescent screen assembly includes a patterned light-absorbing matrix that defines a first set of fields, a second set of fields, and a third set of fields. A first blocking layer is formed over the second set of fields and the third set of fields. A first pigment is then applied to the first set of fields to form a first color filter. The first blocking layer is removed from the second set of fields and the third set of fields, and a second blocking layer is formed over the third set of fields and the first color filter in the first set of fields. A second pigment is then applied to the second set of fields to form a second color filter. The second blocking layer is then removed from the third set of fields and the first color filter in the first set of fields.

Abstract: A display device comprises a color filter pattern between a phosphor pattern and a display window. For blue, the thickness (t2) of this color filter pattern is more than 2.5 micrometer, preferably 5-7 micrometer, and/or for red said thickness is 0.25-1.5 micrometer. The red and/or blue color filter patterns are provided by means of a non-linear photoresist. This enables an improved contrast (LCP) to be achieved.

Abstract: A color cathode ray tube is disclosed, that comprises an optical filter layer 2 formed on an inner surface of a glass panel 1, a thin film formed on a front surface of the optical filter layer 2 and composed of a metal oxide, and a fluorescent substance layer 4 formed on the thin film 3 corresponding to a pattern of the optical filter layer 2. The surface state of the thin film 3 is rougher than the surface state of the optical filter layer 2 and similar to the surface state of the fluorescent substance layer 4. Thus, the optical filter layer 2 sparsely contacts the fluorescent substance layer 4. Thus, the influence of the optical filter layer 2 to the fluorescent substance layer 4 can be reduced. Consequently, fluorescent substance particles of the fluorescent substance layer 4 can be suppressed from breaking, dropping, and so forth. Thus, an excellent fluorescent surface can be obtained at high throughput.
