Abstract: A substantially rectangular glass panel for a cathode ray tube is made of a glass having a linear X-ray absorption coefficient of at least 34 cm−1 at a wavelength of 0.6 Å, with the dimensions of the panel satisfying the condition of 0.07≦T/D≦0.09; and the panel is prestressed so that the surface of the face of the panel has a residual compressive stress ranging from 5 to 25 MPa, wherein T is the central thickness of the face of the panel in inches and D is the maximum diagonal line length of the face of the panel in inches.
