A cathode-ray tube having a face plate which includes a phosphor layer provided at the inner surface side of a glass plate and an optical interference filter provided between the phosphor layer and the inner surface of the plate. The optical interference filter is constituted by high- and low-refractive index layers. The outermost layer of the optical interference filter in contact with the phosphor layer is an Al2O3 layer or a ZrO2 layer having a physical thickness of 10 nm or more. The high-refractive index layer of the optical interference filter preferably consists of TiO2, and its low-refractive index layer preferably consists of Al2O3.
