Patent ID: 8797475

Claim:
A lighting device, comprising: a light source; a chassis storing the light source therein; an extending member extending along an inner surface of the chassis; a holding member fixed to the chassis and holding the extending member to the chassis such that the extending member is sandwiched between the holding member and the chassis; and a restricting part restricting positional relationship of the holding member with respect to the extending member such that a gap is provided between the holding member and the extending member; wherein the extending member includes a light source substrate with the light source and a reflection member that reflects light from the light source, the light source substrate and the reflection member are overlaid and sandwiched between the holding member and the chassis; the reflection member is arranged on the light source substrate on the side opposite to the chassis, and has a light source insertion hole through which the light source is passed, the light source insertion hole that is provided at a position overlapping the light source in a plan view; a diffuser lens that diffuses light from the light source is arranged at a position overlapping the light source in a plan view on the light source substrate on the side opposite to the chassis; and the reflection member includes a first reflection member and a second reflection member, the first reflection member that has the light source insertion hole through which the diffuser lens can be passed, the second reflection member that is arranged between the light source substrate and the diffuser lens at a position overlapping the light source insertion hole of the first reflection member in a plan view, the second reflection member that reflects light toward the diffuser lens.
