Abstract

A color cathode ray tube (10b) lacking an inner shield (16) is disclosed which is characterized in that the inner surface of the funnel is coated with a conductive layer (18b), the conductive layer being made of a high permeability metal or an alloy of high permeability metals, or being made of a high permeability metal or an alloy of high permeability metals and a high resistance material. According to the present invention, the inner shield is totally removed, and therefore, the manufacturing process for the products is simplified and the manufacturing cost is saved.
