Abstract

PURPOSE:To obtain a very good picture characteristic free of color separation and color phase irregularity by forming a mechanically strong mask frame by using a mask frame and body and the first and second flanges and adhering a shadow mask to the inner surface of the frame body. CONSTITUTION:On the side edge portions of the fluorescent screen of the mask frame body 301, the mask frame 30, consisting of the first flange 302 formed by bending in the with drowing direction of the tube axis Z and the second flange 303 formed by bending in the approaching direction of the tube axis on the end edge portion opposite to the fluorescent screen of the frame body 301, is provided and also the supporter 34, consisting of the spring 32 and the bimetal 33 supported on the panel pin 31 attached to the inner surface of the side wall 23 of the frame body 301, is provided. The electron beam 28 is scanned on the fluorescent screen 21 through a great number of openings provided in the available area 291 by a deflector to reproduce color image on the fluorescent screen. Thus, a very good picture characteristics free of color separation and color phase irregularity can be obtained.
