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 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.
