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： A flat panel for a cathode ray tube includes a faceplate portion, a skirt portion and a blend round portion joining the faceplate portion with the skirt portion. A point where an external contour of the faceplate portion meets an external blend round contour of the blend round portion is defined as a first point and a point where an external contour of the skirt portion meets the external blend round contour is defined as a second point. The external blend round contour is formed between an imaginary arc whose end points coincide with the first and second points and a line segment whose end points coincide with the first and second points, or is the line segment. The imaginary arc is smoothly connected to the external contours of the faceplate portion and the skirt portion at the first and the second point.
