The present invention relates to a lighting device including a plurality of light source units U including at least LEDs 16 and light guide plates 18. The light source units U are arranged in one direction such that gaps S are provided between the adjacent light guide plates 18. Each light guide plate 18 has a first light exit surface 36A. The light guide plate 18 receives light from the LED 16. Light L1 exits from the first light exit surface 36A. A diffuser 15b that receives the light L1 from the first light exit surface 36A is disposed so as to face the first light exit surface 36A. Reflection sheets 24 that reflect light are disposed on an opposite side from the diffuser 15b so as to cover the gaps S. Each light guide plate 18 has a second light exit surface 36B in an edge portion that faces the gap S on the opposite side from the diffuser 15b. The second light exit surface 36B is formed such that light L2 exits therethrough, reflects off the reflection sheet 24 and travels to the diffuser 15b via the gap S.
