    • PROBLEM TO BE SOLVED: To provide an illuminating device with high in-plane uniformity of luminance by having no dark part to be made in a joint section between planar light source panels.
      SOLUTION: The illuminating device 1 is provided with a plurality of planar light source panels 2 and a plurality of light diffusion reflecting plates 3 arranged on a light emitting side of the planar light source panels 2. The light diffusion reflecting plates 3 have rectangular bottom surfaces arranged on a light emitting region on the planar light source panel 2, light emitting surfaces 3a are approximately the same size as a planar contour of the surface light source panels 2 and side surfaces 3c are formed to be inclined diagonally outward from the bottom surfaces to the light emitting surfaces 3a. The light diffusion reflecting plates 3 which are adjacent to each other are arranged to be in contact with each other without any gap and the light emitting surfaces 3a are arranged to be continuous.
