Abstract
This is a cathode ray tube having a panel provided with a colored layer on an outer surface of a face portion, wherein an emission luminance ratio is 75% or higher in a lowest part relative to a highest part, and a diffuse reflectance ratio is 90% or higher in a lowest part relative to a highest part in an image display area of the face portion. Due to this configuration, a cathode ray tube with a natural appearance can be obtained in which a luminance difference or a contrast difference is not perceived in the entire area of the face portion.
