A projection display apparatus includes a housing case housing a light source unit, a light valve, and a projection unit. The plurality of solid light sources are connected to a plurality of fibers, respectively. Light outputted from the plurality of fibers bundled by a bundle unit is guided to the light valve through a rod integrator. The rod integrator is arranged so that the a longitudinal direction of the rod integrator extends in a horizontal direction parallel to the projection surface. The light valve is arranged closer to a projection-side sidewall than the rod integrator.
