Planar light source and the method of manufacturing the same

A planar light source comprising:

• one or more light sources each having a pair of electrodes extending on one face of the one or more light sources within a perimeter of the one face of the one or more light sources and a light adjusting member disposed on another face opposite the one face of the one or more light sources in a plan view;
• an insulating base having a first side and a second side opposite each other relative to the insulating base, the first side at which the one or more light sources are located;
• a wiring layer electrically connected to the electrodes and disposed on the second side of the insulating base;
• a light reflective member located at the first side relative to the insulating base and defining, for each of the one or more light sources, a pair of first through holes at positions aligned with the electrodes on a one-to-one basis, an opening of each of the first through holes not running over an outline of the light source in the plan view;
• and
• for each of the one or more light sources, a pair of conducting members respectively disposed in the first through holes and electrically connecting the electrodes to the wiring layer, wherein
• an opening of each of the first through holes for each of the one or more light sources extends within an outline of the light source in the plan view.
