摘要：
Disclosed in this invention are a cathode ray tube, especially glare type one, characterized in that a two-layer composite film consisting of a transparent electroconductive film and a protective film formed thereon is coated on the front panel so that surface glossiness thereof as measured by JIS Z-8741 Method 2 will become 80% or above, and a process for producing the cathode ray tube.
