摘要： A shadow mask opposing a phosphor screen includes a substantially rectangular mask body having a number of electron beam passage apertures, and a substantially rectangular mask frame having four side walls supporting a periphery of the mask body. Among the side walls, a pair of long side walls each has a central connecting portion which is located at a central portion thereof in lengthwise direction and fixed to the mask body, and a pair of protruding portions which are provided on both sides of the central connecting portion in the lengthwise direction and protrude in a direction apart from the mask body. Each protruding portion defines a gap between the side wall and the mask body, and a width of the gap gradually increases as it goes far from the central connecting portion.

摘要： A color cathode ray tube comprises a panel having an effective portion. The outer surface in the effective portion of the panel is substantially flat or forms a slightly curved plane with a small curvature. The inner surface of the panel has a substantially infinite curvature radius in a direction of the longer axis in at least a central portion of the panel and is curved in a direction of the shorter axis. A difference in thickness of the effective portion of the panel between the central portion and the edge portions diagonally apart from each other exceeds 8 mm and does not exceed 20 mm, and the transmittance of the glass in the central portion of the effective portion is at least 70%. The particular construction enables the vacuum envelope of the color cathode ray tube to exhibit a mechanical strength high enough to sufficiently withstand the atmospheric pressure, though the effective portion of the panel is flattened. The vacuum envelope also exhibits a mechanical strength high enough to hold the curved surface of the shadow mask. Further, deterioration of brightness can be prevented in the color cathode ray tube of the present invention.

摘要： A shadow mask of a color cathode-ray tube has a substantially rectangular mask main body and a substantially rectangular mask frame fixed to a skirt portion of the mask main body. The mask main body has a curved effective surface formed with a large number of electron-beam passage apertures and opposing the phosphor screen, a non-aperture portion surrounding the outer periphery of this effective surface, and a skirt portion formed in a bent on the outer periphery of the non-aperture portion. The mask main body has a long axis extending in a horizontal direction and crossing with a tube axis, and a short axis extending in a vertical direction and crossing with both the tube axis and the long axis. The effective surface and the non-aperture portion of the mask main body are formed in a curved surface having a radius of curvature in the short axis direction. At each long side of the mask main body, each end portion of the short axis of the effective surface and the non-aperture portion is recessed from any other adjacent part, in a direction leaving from the phosphor screen along the tube axis. The radius of curvature in a short axis direction near the short axis of the effective surface and the non-aperture portion of the mask main body is smaller than the radius of curvature in the short axis direction at other parts.

摘要： In a color cathode ray tube in which the external surface of an effective portion of a panel has a flat surface or a slight curvature, the shadow mask is set such that the layout distance between electron beam through hole array near the long side of an effective surface of the shadow mask is larger in the vicinity of the short axis than the layout distance at the center of the effective surface. Further, the layout distance becomes gradually smaller in direction away from the short axis, and thereafter, the layout distance changes to an increase. In the vicinity of the short side of the effective surface, the layout distance becomes equal to or larger than the layout distance near the short axis. Therefore, the curvature of the shadow mask and the electron beam through hole array are set in proper condition, and mislanding of beam landing due to deformation or oscillation of the shadow mask can be reduced. At the same time, howling of the phosphor screen can be minimized.
