Abstract
A flat type cathode ray tube is disclosed which includes a flat envelope formed of a flat panel and a dish-shaped funnel, a first deflection system composed of a back electrode and a phosphor screen which are both located within the envelope in opposing relation with each other, a neck portion coupled to the envelope, the neck portion extending in the surface direction of the flat envelope having therein an electron gun, and a second deflection system formed of electro-static deflection plates which are so located within the envelope that they oppose each other across the path of the electron beam emitted from the electron gun to the first deflection system with respect to a thickness direction of the flat envelope. In this case, a projecting portion is provided from the peripheral portion of the funnel for molding material.
