1. A device for displaying an image including:
- a screen,a support structure, comprising support elements for supporting said screen, whereby each of said support elements is in contact with said screen in a contact area,light sources, each of which illuminating an illuminated area on said screen;
whereby said light sources are positioned so that said illuminated areas generated by light sources adjoining one another are overlapping and thus create an overlapping area, the contact areas between said support elements and said screen being superimposed on said overlapping areas.

Abstract
A device for displaying an image has a screen, a support structure with support elements for supporting the screen, and a plurality of light sources. Each support element is in contact with the screen at a contact area. Each light source illuminates an illuminated area on the screen. The light sources are positioned such that illuminated areas generated by light sources adjoining one another are overlapping and thus create an overlapping area. The contact areas between support elements and the screen are superimposed on the overlapping areas.

4. The device according to claim 4, wherein the thickness of said transparent portion is less than a value emax given by the following relation:
-
emax=(l+L)cotan(α
/2)−
hwherein h is the shortest distance between the light sources and said transparent portion, L is the distance between each support element and the nearest light sources, l is the distance between the middle and the edge of said contact area, and α
is the direct illumination angle of said light sources.
