The panel has a backlight device (1) for backlighting to be back lighted surface (18), and a light source (10) delivering radiation (R), where the surface has an LCD screen (E). A reflection surface (12) is arranged opposite to a radiation cone of the source. Another reflection surface (14) is arranged opposite to a portion of the former reflection surface and opposite the surface to be back lighted to reflect the radiation reflected by the former reflection surface on a portion of the to be back lighted surface, where the reflection surfaces are parabolic, elliptical or hyperbolic in shape. |
