摘要： The present invention is related to a flat panel for cathode-ray tube capable of securing a large viewing area in the flat panel which is fitted into a window of a cabinet. In accordance with the panel of the present invention, stepped portions are formed along an edge of a face to fit the panel into the window of the cabinet. A depth from a surface of the face to a surface of the stepped portion is set to satisfy a condition of 2≧Tf/Tc≧0.7 where Tf is a vertical distance from a starting point of the stepped portion to an inner surface of the panel and Tc is a thickness of the center of the face. The panel in accordance with the present invention can provide perceptual flatness to a viewer; improved implosion-proof characteristics; and a structure capable of enduring an external mechanical impact. Further, the panel having a precise structure can be manufactured by a press-molding process.

摘要： In a cross-section including a tube axis, assuming that T1 represents a thickness of a funnel at a point on an outer circumferential surface of the funnel, which is placed at the same position in a tube axis direction as that of an end of a horizontal deflection coil on a phosphor screen side, and T2 represents a thickness of the funnel at a point on the outer circumferential surface of the funnel, which is placed at the same position in the tube axis direction as a position 7 mm away from the end of the horizontal deflection coil on the phosphor screen side to the phosphor screen side along the tube axis, the funnel includes at least one cross-section including the tube axis satisfying a relationship: T2/T1≧1.18. Owing to this, cone halation can be prevented while an X-ray leakage amount is limited to a predetermined value or less.
