Abstract: A phosphor screen with metal back of the present invention has a degree of adhesion of 30% or more in the ratio of the contact area of a phosphor layer (2) and a metal back layer (3). The deterioration (film burning) of emission brightness in FED can be suppressed and the brightness characteristics can be improved. The film thickness of the metal back layer is set to 50 to 100 nm and the light transmittance thereof is set to 10% or less to provide a highly bright display with excellent reflectivity. The phosphor screen with metal back can be formed by transferring a metal film onto the phosphor layer formed on the internal surface of a translucent substrate by using a transfer film.

Abstract: There is provided a cathode-ray tube including an envelope having a neck, a funnel and a panel fused to the funnel by using frit glass, the outside of the panel being near flat, the inside of the panel having a predetermined curvature, in which 1.7≦T2/T1≦2.3 when T1 is the thickness of the center of the panel and T2 is the thickness of the diagonal corner of the panel, and a panel inside tensile stress at the fused portion of the panel and funnel is less than −1.3876x+128.24 (Kgf/cm2) when the size of the effective picture area of the cathode-ray tube is x(unit: cm). The panel inside tensile stress at the fused portion of the panel and funnel is maintained below a predetermined value to mitigate breakage inside the furnaces that occurs when the cathode-ray tube having the panel whose outside is near flat and whose inside has a predetermined curvature is reproduced, thereby improving the salvage rate.

Abstract: The outer surface of a panel effective section of a vacuum envelope is substantially flattened. A phosphor screen is formed on the inner surface of the effective section and includes stripe-shaped phosphor layers and light absorption layers arranged in parallel. The panel effective section is formed such that a corner portion is 8 mm to 15 mm thicker than the central portion and the transmittance of the central portion is set at 40% to 60%. The phosphor screen is formed such that the ratio of the width of a light absorption layer to the pitch of phosphor layers in the central portion of the panel effective section is larger than or equal to that in the peripheral portion thereof. A shadow mask is opposed to the phosphor screen and has a mask body in which a number of electron beam passage apertures are formed. The pitch of apertures formed in the peripheral portion of the mask body is 1.3 to 1.4 times as large as that of apertures formed in the central portion thereof.

Abstract: A viewing screen (100) for a display device (115) includes a glass substrate (110) having a thermal coefficient of expansion within a range of 3.5×10−6−4.5×10−6 °C.−1. Viewing screen (100) further includes a black matrix (111), which is affixed to glass substrate (110), and which includes a black surround, a ductile metal, and lead titanate. A method for fabricating viewing screen (100) includes the steps of: adding to a black surround paste a ductile metal paste, adding to the black surround paste lead titanate particles, depositing the black surround paste on glass substrate (110), and heating the black surround paste and glass substrate (110) to affix the black surround paste to glass substrate (110), thereby forming black matrix (111). The ductile metal paste and lead titanate particles are added in amounts sufficient to realize an extent of cracking in black matrix (111) upon repeated heating to a temperature within a range of 450-600° C. that is significantly less than that exhibited by an unimproved black matrix, which is made only from the material of the black surround paste.
