Projection-type display apparatus

A projection-type display apparatus includes an optical engine that forms an image with a laser beam from a laser light source; and an optical fiber that connects the laser light source and the optical engine. The optical engine includes a rod integrator that equalizes an optical-intensity distribution of the light beam output from the laser light source, and a rod fiber-fastening unit that fastens the rod integrator and the optical fiber to face each other such that a gap between an input facet of the rod integrator and an output facet of the optical fiber is large relatively to a wavelength of the light beam propagating through the optical fiber.
