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.
