A projection display apparatus includes a housing case housing a light source unit, a light valve, a projection unit, and a cooling unit. A size of the housing case in an orthogonal direction to a projection plane is smaller than a size of the housing case in a horizontal direction parallel to the projection plane. The projection unit is arranged at substantially center of the housing case in the horizontal direction parallel to the projection plane.
