Abstract
A light source device of the present disclosure includes a light source unit including a first coupling part which is disposed in the gap and electrically couples the first and second light emitting element groups, and a first regulatory member which is disposed between a light guide member and a base substrate, and regulates a position of a light guide member with respect to a support member. The first light emitting element group has a configuration in which a plurality of first light emitting elements is coupled in series so that a current flows along a first direction, and the second light emitting element group has a configuration in which a plurality of second light emitting elements is coupled in series so that a current flows along a second direction opposite to the first direction. The first regulatory member is disposed to overlap the first coupling part.
