Abstract
A light source device includes a substrate, a light emitting unit, a frame, a light permeable member, and a metal shield. An upper electrode layer and a lower electrode layer of the substrate are respectively disposed on two opposite sides of the substrate, and are electrically coupled to each other. The light emitting unit is disposed on the upper electrode layer. The frame is disposed on the substrate and is arranged around the light emitting unit. The light permeable member is disposed on the frame and covers the light emitting unit. The metal shield is fixed to an inner side of the frame and is connected to the ground pad of the upper electrode layer. The metal shield is arranged around the outer side of the light emitting unit.
