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.

摘要： A display device including a display screen having an optical film provided thereon. The optical film is a porous thin film made of fine magnesium fluoride particles and a binder containing a condensate of a silane compound having a fluoroalkyl group, a co-condensate of the silane compound and silicon, or a co-condensate of the silane compound and a metal oxide compound. The combination of the specific binder and fine magnesium fluoride particles permits forming a porous optical film having a surprisingly high mechanical strength, excellent resistance to humidity and reduced external light reflection from the display plane.

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.
