Abstract
A cathode ray tube having a double-layer low-reflective coating layer, or a triple-layer low-reflective coating layer including a high-refractive transparent conductive layer formed on the outer surface of a face plate thereof, and a low-refractive smooth transparent layer formed on the outer surface of the high-refractive transparent conductive layer, or a low-refractive transparent layer having concavities and convexities formed on the low-refractive smooth transparent layer, wherein yellow dye or pigment is added to at least one of said three layers, whereby the reflection spectrum in the visible ray region can be flattened so that a cathode ray tube is obtained in which reflection in the short wavelength region and long wavelength region can be reduced, coloring can be suppressed, and natural external reflected light can be obtained.
