ABSTRACT:
A cathode ray tube is provided, and more particularly, a cost-effective cathode ray tube effective for minimizing deterioration of color purity and obtaining a sufficient margin for a beam strike neck (BSN) phenomenon by moving a ½ center (deflection center) closer to a panel without changing the curvature of a funnel or the thickness of a glass inside the funnel.
