To provide a projection type display device using a laser light source, reducing the overall thickness of the device and eliminating annular color unevenness which is highly likely to occur when viewing a 3D video image using a liquid crystal shutter system.

In this projection type display device 1, an image is formed by an optical engine 30 using a laser beam from a laser light source 10, and the laser beam emitted from the optical engine 30 is enlarged and displayed on a screen 51. The laser light source 10 and the optical engine 30 are connected to each other by an optical fiber 20. The optical engine 30 includes a rod fiber fixing part 36 disposed in the optical engine 30, wherein the rod integrator 31 and the optical fiber 20 are disposed so that an incident end face of the rod integrator 31 for making uniform the distribution of quantity of laser beams from the laser light source 10 faces an exit end face of the optical fiber 20 with a space larger as compared with the wavelength of light propagated by the optical fiber 20, and fixed by the rod fiber fixing part.
