Abstract
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.
