Abstract
A planar lighting device according to an embodiment includes a light guide plate, a plurality of light sources, and a strip-shaped member. The light guide plate has a side surface and two main surfaces. One of the two main surfaces emits light entered from the side surface. The light sources face the side surface and are arranged in a longitudinal direction of the side surface and emit light that enters the side surface. The strip-shaped member extends in the longitudinal direction of the side surface and is adhered to a region on at least one of the two main surfaces closer to the light sources. The strip-shaped member includes non-adhesive portions disposed at positions facing regions of the at least one of the two main surfaces in front of the light sources. The non-adhesive portions do not adhere to the light guide plate.
