ABSTRACT:
A color selection electrode (7) is suspended from the corners of the upright edge (3) of a display window (2) by means of resilient elements (25) which extend substantially perpendicularly to the electron beams deflected towards the corners. The resilient elements (25) have apertures (28) with which the resilient elements (25) are placed on mandrils (31). The mandrils (31) are embedded in the corners of the upright edge (3) of the display window (2) perpendicularly to the planes of the resilient elements (25). A screening cap for screening the electron beams from the earth's magnetic field is connected on the mandrils (31) in such manner that the screening cap exerts no pressure on the resilient elements (25).
