Abstract: A projection display device includes a light source part including a first light source part that emits first color light and a second light source part that emits second color light having an emission intensity distribution different from that of the first color light, an image generator that generates an image on a basis of light emitted from the light source part, and a projection lens that projects the light outputted from the image generator onto a projection surface and has a projection optical axis that is shifted from a reference optical axis of the device as a whole. An emission optical axis of the first light source part is shifted to a direction opposite to a direction of the projection optical axis having been shifted.

Abstract: The invention aims to provide small-sized and highly-reliable light converter and light source unit, as well as a projector each of which makes it possible to cool down heat generated in a fluorescent body in a motorless manner. A light converter of the disclosure includes: a fluorescent body (12) that is excited by excitation light; a first light-collecting lens (11A) that has a lens surface to which the fluorescent body is bonded, and causes the excitation light to enter the fluorescent body; and a heat-dissipating member (14) to which the lens surface is adhered at least around a region to which the fluorescent body is bonded.
