Display device used to display a signal obtained by sampling and stored in a memory and recovered by interpolation points or interpolation vectors and in order to suppress the effect of light fluctuation of the interpolation segments (P) which represent horizontal or somewhat sloping portions of the light trace to be displayed, comprising processing means which, associated with each interpolation segment (P) which have a predetermined energy and are located on one line in one of the fields, for generating at least one and generally two further parallel, so-called anti-flicker segments (I.sub.A) and (I.sub.B) which have a two times weaker energy and are located in the other field, that is to say on one or two lines of the further field which lines enclose the relevant line in the first field.
