Abstract:
A cathode ray tube (CRT) comprising:a glass panel containing elemental neodymium in a concentration of 0.1-1.5 wt % and elemental praseodymium in a concentration of 0.1-0.7 wt %, a phosphor screen in which red, green, and blue phosphors are located in a black matrix in a pattern, at an inside of the panel, and a low-reflectivity coating layer at an outside of the panel, the low-reflectivity coating layer having a reflectivity of no more than 2.0% near 480-600 nm, the low-reflectivity coating layer including a first coating layer of silica, and a second coating layer of a material having a refractive index higher than silica and selected from the group consisting of indium tin oxide, antimony tin oxide, and silver.
