An object of the present invention is to provide a CRT for improving brightness without changing a conventional electron gun, a light emitting layer, etc. A color cathode ray tube according to the present invention is characterized in that both or one of a panel glass 3 and a safety glass 1 used on a front face of the color cathode ray tube uses glass having characteristics in which spectroscopic transmittance to an electromagnetic wave near 580 to 700 nm in wavelength is relatively higher than spectroscopic transmittances to electromagnetic waves near 430 nm and 530 nm in wavelength.
