Abstract
(EN)
Provided is an edge-light type lighting device that has a plurality of lighting subareas, wherein of the plurality of lighting subareas, the outlines of 2 adjoining lighting subareas have mutually complementary shapes, so that the boundary part between the 2 adjoining lighting subareas forms a rugged shape.
