Abstract
This invention relates to a color display tube having a color selection electrode which is suspended from the display window by means of pin-shaped members which are inserted in the upright edge 3 of a display window. The pin-shaped members have a spherical free end 16 portion which engages in an aperture of a conical portion of the flat resilient suspension element attached to the corners of the mask. To avoid the flat resilient suspension element from lying against the pin-shaped member, the central axis A of the pin-shaped member forms an angle .alpha. of from 5.degree. to 20.degree. with the X-Y plane.
