<p>PROBLEM TO BE SOLVED: To provide a lighting device capable of lightening surrounding areas.SOLUTION: A lighting device 10 includes a light guide panel 22, a diffuser panel 23 and a light emitting element 36. The light guide panel 22 includes an incident surface 28 which is provided on a side part 27 and also on an opposite side to a main irradiation direction, and an emission surface 29 provided to face the incident surface in the main irradiation direction, so as to introduce the light incident from the incident surface 28 and emit the light to the main irradiation direction from the emission surface 29. The diffusion panel 23 covers the outside including the side part 27 of the light guide panel 22. The light emitting element 36 has a light emitting part 36a emitting light. Light emitted from the light emitting part 36a is incident on the incident surface 28 of the light guide panel 22 and part of the light emitted from the light emitting part 36a is incident on the side part 32 of the diffusion panel 23 covering the side part 27 of the light guide panel 22.</p> |
