A double-sided display screen, comprising: - two flat displays, each having a front and a rear side, - a backlighting element, - wherein the displays are arranged at a distance from each other with their rear sides facing one another, with the backlighting element in the intermediate space defined by the displays, and the backlighting element is capable of controlled light emission in two opposite directions, and - wherein the backlighting element comprises a light guide plate with an LED lighting element, - wherein the light guide plate has two opposite end faces and a front and a rear face connecting them, and - on the front side and the rear side of the light guide plate reflector dots (301, 302) are printed or moulded, and - the reflector dots (301, 302) on the front side and on the rear side respectively form a grid with rows aligned transversely to a light incidence direction and columns aligned parallel to the light incidence direction, wherein adjacent columns of the grid of reflector points (301, 302) have a constant column spacing (Ah), and the grid of the reflector points on the front side and the grid of reflector dots on the rear side are offset with respect to each other, characterised in that • one LED lighting element is present on each of the two opposite end faces, and • row spacings (Av1, Av2, Av3) between neighboring rows of the grid of reflector points (301, 302) decrease toward the center of the display, and • within a row, a diameter of a reflector point which is closer to the centre is smaller than a diameter of an edge-ward reflector point, such that on the front side and the rear side respectively an exit luminance taking into account the luminance and the exit radiation cone of the lighting elements is constant over the surface, wherein the values of the luminance on the front side and the rear side of the light guide plate may be different. - two flat displays, each having a front and a rear side, - a backlighting element, - wherein the displays are arranged at a distance from each other with their rear sides facing one another, with the backlighting element in the intermediate space defined by the displays, and the backlighting element is capable of controlled light emission in two opposite directions, and - wherein the backlighting element comprises a light guide plate with an LED lighting element, - wherein the light guide plate has two opposite end faces and a front and a rear face connecting them, and - on the front side and the rear side of the light guide plate reflector dots (301, 302) are printed or moulded, and - the reflector dots (301, 302) on the front side and on the rear side respectively form a grid with rows aligned transversely to a light incidence direction and columns aligned parallel to the light incidence direction, wherein adjacent columns of the grid of reflector points (301, 302) have a constant column spacing (Ah), and the grid of the reflector points on the front side and the grid of reflector dots on the rear side are offset with respect to each other, • one LED lighting element is present on each of the two opposite end faces, and • row spacings (Av1, Av2, Av3) between neighboring rows of the grid of reflector points (301, 302) decrease toward the center of the display, and • within a row, a diameter of a reflector point which is closer to the centre is smaller than a diameter of an edge-ward reflector point,
