Abstract
A light source device includes: a base substrate; a plurality of light emitting elements disposed on the base substrate along each of an X-direction and a Y-direction crossing the X-direction; and a first polarity terminal and a second polarity terminal for supplying power to the plurality of light emitting elements. The first polarity terminal and the second polarity terminal project from one side of the base substrate in the X-direction as viewed in a Z-direction orthogonal to the X-direction and the Y-direction.
