A method of manufacturing a color display tube in which after the envelope is formed the shadow mask is displaced relative to the display window via movable positioning members provided in the envelope. After the color display tube is assembled a test pattern is displayed on the display screen and is optimized by means of positioning members 23, such that the shadow mask is accurately aligned relative to the display screen 6. The adjusted position is fixed by forming a number of welds, using a laser 33, between the connection means 12 and the support elements 10 in the display window 1.
