ABSTRACT:
Disclosed is a cathode ray tube, comprising a panel of which outer surface is substantially flat and inner surface has a designated radius of curvature, a funnel connected to the panel, an electron gun housed in the funnel, emitting electron beams, a deflection yoke for deflecting the electron beams, and a shadow mask for discriminating the electron beams in colors, wherein a ratio (%) of a corner portion of the panel to a thickness at a central portion of the panel is in a range of 150%˜230%, and design sizes of the panel satisfy a relation ofCFT×USDIBRD×100≤1100⁢⁢mm(wherein, CFT denotes a thickness at the central portion of the panel, USD denotes a diagonal length of an effective surface of the panel, and IBRD denotes 2×a distance from the center of the panel to the center of a radius of curvature from the corner portion of the panel).
