| Zusammenfassung: | PURPOSE:To restrain vibration of grid electrode structure in directions on both a fluorescent screen side and an electron gun side of a metal fine portion so as to improve beam mislanding due to vibration. CONSTITUTION:Color selecting grid electrode structure 1 is provided with numerous slits 2 arranged in a stripe form with predetermined pitches by etching. The grid electrode structure 1 is disposed in a frame 3 in an approximately flat state stretched in the vertical direction. Metal lines 5a, 5c and 5b, 5d are stretched in contact with the front and back surfaces of the grid electrode structure 1, respectively. |
