摘要
PURPOSE: A cathode ray tube is provided to improve adhesive strength of a contact portion between a conductive film and a double coating graphite film of a funnel, by using graphite particles having different particle sizes. CONSTITUTION: A cathode ray tube comprises a panel having an inner surface on which a phosphor screen is formed such that the phosphor screen emits light by the impingement of the electron beams emitted from an electron gun; and a funnel coupled to the panel such that the interior of the funnel and panel assembly is maintained at a vacuum state. The funnel has an inner surface on which a conductive film(210) is formed for electrical conduction; and a double coating graphite film(230) formed on the conductive film. The double coating graphite film has conductive particles having different particle sizes.
