Abstract:
1. A panel of a slim cathode ray tube constructed such that the deflection angle of an electron beam is 110 degrees or more, the slim cathode ray tube including a tube part constituted by joining the panel and a funnel with each other, wherein the panel includes a face part, on which a picture appears, a side wall disposed around the face part such that the side wall is bent toward the funnel, and a seal edge formed at the side wall, the panel being joined with the funnel at the seal edge, wherein the thickness of the center of the face part is Tc, the thickness of the long side of the seal edge is Tx, the thickness of the short side of the seal edge is Ty, and the thickness of the diagonal part of the seal edge is Td, the panel is constructed such that the following inequalities are satisfied: 0.8≦Tc/Ty≦Tc/Tx≦1.0≦Tc/Td and Td<Tx<Ty, and the side wall has an outer skirt angle of 0.5 to 1.5 degrees, wherein the panel is formed substantially in a rectangular structure, and the outer skirt angle is set such that the following inequality is satisfied: the outer skirt angle at the short side>the outer skirt angle at the diagonal part>the outer skirt angle at the long side.
