Abstract

A light source device and a display device capable of preventing a problem of torsion occurring in a back chassis due to an unevenness in a temperature distribution are provided. In a light source device including: a light guide plate that outputs light incident from one side face from one face; a light source that is arranged on the one side face side of the light guide plate; and a back chassis that has a bottom arranged to face the other face of the light guide plate, by forming a reflection film reflecting light incident from the light guide plate to the light guide plate in a heat absorption plate portion that is arranged between the light guide plate and the bottom of the back chassis and absorbs heat emitted from the light source, the heat absorption plate portion absorbs heat generated from the light source and achieves the role of a reflection sheet.
