Abstract: A planar light source includes: a support member including a wiring substrate, a light guide member, a light source disposed in a hole of the light guide member, and a first reinforcing member disposed on the support member and surrounding the light guide member in a plan view. The first reinforcing member includes first and second portions extending in a first direction and facing each other, and includes third and fourth portions extending in a second direction orthogonal to the first direction and facing each other. At least one of the first portion, the second portion, the third portion, and the fourth portion has light reflectivity to light emitted from the light source. In the plan view, the light guide member is located between the first and second portions in the second direction, and is located between the third and fourth portions in the first direction.
