Abstract
A panel for use in a cathode ray tube includes a face portion for displaying picture images, a skirt portion extending backward from a perimeter of the face portion and a blend radius portion joining the skirt portion to the face portion. The panel for use in a cathode ray tube has average outside curvature radius R (mm) of the face portion which satisfies the following relationship: R≧10,000; wedge rate Td/Tc of the face portion which satisfies the following relationship: 2.0≦Td/Tc≦2.6; maximum compressive surface stress σC(MPa) of the face portion and the skirt portion which satisfies the following relationship: −30≦σC≦−15; and tensile bending stress σbt (MPa) at inner surface of the blend radius portion which satisfies the following relationship: σbt≦10.
