Abstract
An image can be projected in a wide angular range while an increase in a beam diameter is suppressed. A light source device according to the present disclosure includes: a plurality of light emitting elements divided into a plurality of regions; and an optical unit that includes a plurality of first lens groups having a first focal length and corresponding to the regions of the light source unit on a one-to-one basis, and a second lens group having a second focal length and emitting light having passed through the first lens groups. In the optical unit, for each of the regions, the first focal length is smaller than zero, the second focal length is larger than zero, and each composite focal length of each of the first lens groups and the second lens group is larger than the second focal length.
