ABSTRACT:
A fluorescent screen including a plurality of parallel stripes of three colour phosphors is prepared by projecting light from a linear light source positioned in parallel with the stripes on photosensitive substances coated on the inner surface of the panel through a plurality of stripe shaped perforations of a colour selecting member, each divided into a plurality of slit shaped sections by means of bridges. The linear light source is constituted by reciprocating a point light source in parallel with the stripe shaped perforations.
