Abstract: A light source device includes a laser light source, a first adjustment mechanism, a second adjustment mechanism, and a mirror. The laser light source emits laser light. The first adjustment mechanism is configured such that the laser light from the laser light source is incident thereto, and performs an emission angle adjustment of the laser light and a focus adjustment of the laser light. The second adjustment mechanism is configured such that the laser light from the first adjustment mechanism is incident thereto, and performs a positional adjustment of the incident laser light. The mirror is configured such that the laser light from the second adjustment mechanism is incident thereto, and emits the incident laser light in a predetermined direction. An image display apparatus includes the above light source device.
