PROBLEM TO BE SOLVED: To provide a laser projector including a smaller number of components as compared with the conventional laser projector. SOLUTION: A laser projector includes a green laser 106, a two-wavelength laser 302, a PBS 304, a collimator lens 112, a two-axis galvanometer mirror 114, a group of lenses 116, and a screen 118. The green laser 106 emits a green laser beam. The two-wavelength laser 302 emits red and blue laser beams. The PBS 304 is provided at the position where respective optical paths of laser beams emitted from respective lasers cross each other to cause these optical paths to coincide with each other.
