Illumination system and display device

An illumination system for illuminating a display device, which illumination system is provided with a light-emitting panel comprising

• a front wall and, opposite thereto, a rear wall as well as first and second light-transmitting edge surfaces which are situated between the front wall and the rear wall,
• at least one first light source being associated with the first edge surface and at least one second light source being associated with the second edge surface, and
• in operation, light originating from the first light source being incident on the first light-transmitting edge surface, and light originating from the second light source being incident on the second light-transmitting edge surface, said light spreading in the light-emitting panel, wherein
• a first sub-surface of the front wall or of the rear wall of the light-emitting panel is provided with first coupling-out members for coupling light out of the panel, which light predominantly originates from the first light source,
• a second sub-surface of the front wall or of the rear wall of the light-emitting panel is provided with second coupling-out members for coupling light out of the panel, which light predominantly originates from the second light source,
• the concentration of the first coupling-out members near the second edge surface being higher than the concentration of the second coupling-out members, and the concentration of the second coupling-out members near the first edge surface being higher than the concentration of the first coupling-out members, and
• the first and second sub-surfaces overlap.
