Abstract:
A planar light source includes a wiring substrate including an insulating layer comprising a first through-hole, a second through-hole, a first wiring layer, and a second wiring layer; a light source including a first electrode and a second electrode, a light guide member; a first wiring member including a first portion filling the first through-hole and electrically connected to the first electrode and a second portion disposed below the insulating layer, continuous with the first portion, and in contact with the first wiring layer; and a second wiring member including a third portion filling the second through-hole and electrically connected to the second electrode and a fourth portion disposed below the insulating layer, continuous with the third portion, and in contact with the second wiring layer. The first and second wiring layers are arranged at opposite sides of the first and second through-holes in a top plan view.
