FIELD: electrical engineering.
SUBSTANCE: light sources (2) and areas (6) with a gap are installed at substrate (4) so that optical layer (5) and light-emitting surface consisting of outputting surfaces (1 c) are located at the preset distance from each other. At that areas (6) with a gap are located so that they pass from respective gaps and each gap is formed by adjoining optical conductors (1) which are located without overlapping each other.
EFFECT: reduction of the device thickness and improvement of luminescent uniformity without deterioration.
