摘要： A color cathode ray tube includes a faceplate and a phosphor screen provided on the inner surface of the faceplate and including red, green, and blue phosphor layers. A color filter layer is interposed between the inner surface of the faceplate and the phosphor screen. The color filter layer includes color filters opposed individually to the phosphor layers of the phosphor screen and having colors corresponding thereto. Color filters of each color have a higher transmittance for light beams with wavelengths which are in a range of .+-.20 nm of the maximum emission spectrum wavelength of the phosphor layers of the corresponding color than for light beams with wavelengths which are outside the range and which are between 400 nm and 650 nm. A common outside filter for complementing the light absorption properties of the color filters is provided on the outer surface of the faceplate and has a maximum absorption in a predetermined wavelength which is outside the maximum emission spectrum wavelengths of the red, green, and blue phosphor layers.

摘要： A method of manufacturing a display screen provided with a filter pattern comprising a first pigment pattern and a second pigment pattern, which comprises the steps of, forming a first pigment layer by coating a solution containing a first pigment on a surface of a substrate and drying the resultant coated layer, forming a first pigment pattern by subjecting the first pigment layer to a patterned light exposure and developing the resultant exposed pattern, forming a second pigment layer by coating a solution containing a second pigment on the surface of the substrate including a surface of the first pigment pattern, and forming a second pigment pattern by selectively removing, through rinsing, a portion of the second pigment layer which is disposed on the first pigment pattern. At least either one of the solution containing a first pigment and the solution containing a second pigment contains an adhesion regulating agent so as to cause the adhesion strength between the first pigment pattern and the second pigment layer to become lower than the adhesion strength between the substrate and the second pigment layer, thus allowing a portion of the second pigment layer formed on the first pigment pattern to be selectively removed.

摘要： a cathode ray tube comprises an envelope including a faceplate with an inner and outer surface and an antistatic layer covering the outer surface of the faceplate for discharging static charges accumulating in the faceplate. The antistatic layer is formed by using a solution containing an alcoholate of silicon as main constituent. The antistatic layer contains a stabilizing substance for maintaining antistatic characteristics. The antistatic layer also has light filtering characteristics when the layer contains xanthene dye as filtering substance.

摘要： A color picture tube includes a vacuum envelope having a faceplate, a phosphor screen formed to include semitransparent black light-absorption layers coated on a first region of the faceplate in stripes or in a matrix, and phosphor layers of blue, red and green emitting phosphors coated on a second region of the faceplate in stripes or in dots, and an electron gun, arranged within the vacuum envelope, for emitting and focusing electron beams. End portions of the phosphor layers extend over the black light-absorption layers, thereby forming overlapped portions. Gaps are provided between the phosphor layers and over the black light-absorption layers, thereby forming light-absorption sections on which no phosphor layer is provided.
