A display panel wherein a conductive polymeric layer (5) is located between the displaying part (1) of a display and the light sources (3) of a backlight system. The conductive polymeric layer (5) exhibits less coloring and less light scattering than ITO and the like, and can prevent or reduce occurrence of image disturbances, such as flutter, moving moiré and flicker, which otherwise would be caused by the fact that the electromagnetic waves radiated from the backlight system act as noise in the operating circuit of the display and which otherwise would be noticeable for a high definition image, a high-speed moving image or a large-sized screen display. L'invention concerne un afficheur comprenant une couche conductrice polymère (5) située entre la partie affichage (1) de l'afficheur, d'une part, et les sources lumineuses (3) du système d'éclairage arrière, d'autre part. La couche conductrice polymère (5) présente une coloration et une diffusion de la lumière moindres que l'oxyde d'étain et d'indium (ITO), ou autre matériau, ce qui permet d'empêcher ou de réduire les phénomènes de perturbation d'image, du type sautillement d'image, moirage au mouvement et papillotement, qui, dans d'autres conditions, surviennent lorsque les ondes électromagnétiques rayonnées par le système d'éclairage arrière agissent comme du bruit dans le circuit d'exploitation de l'afficheur et se manifestent sur une image haute définition, une image en mouvement grande vitesse, ou encore sur un afficheur à écran de grande taille
