ABSTRACT:
The present invention provides a color selecting mechanism for a cathode ray tube in which an enough area of an effective screen area of a color selecting electrode can be ensured. A frame (1) is constituted by a pair of opposite long-side frames (3) and a pair of opposite short-side frames (4). A color selecting electrode (2) is stretched over the upper surfaces (3b) of the long-side frames (3). The frame (1) is formed by the integral molding. The end portions of the upper surfaces (3b) side of the long-side frames (3) are formed into a straight line as if they were cut down. The lower surfaces of connection portions between the long-side frames (3) and the short-side frames (4) are disposed on the same plane. The height of the long-side frames (3) from this plane is formed so as to be higher than the height of the short-side frames (4).
