A projection display device and a light source control method thereof capable of improving visibility of specific information without increasing a manufacturing cost and a power consumption amount are provided. An HUD includes a plurality of light sources that emit light beams with different colors, a projection unit that projects light according to image information among the light beams emitted from the plurality of light sources onto a combiner, and a light source control unit that sequentially emits lights from the plurality of respective light sources according to a predetermined light emission amount pattern. The light source control unit performs control for causing at least one of the light sources other than a specific light source among the plurality of light sources to emit light with a smaller light emission amount than a light emission amount of the specific light.
