摘要
A projection type image display apparatus comprises a light source unit; an integrator unit for mixing luminous fluxes emitted from the light source unit so as to homogenize their light quantity distribution; a curved mirror for bending the optical path of luminous fluxes, which are turned into uniform light by the integrator unit, toward a projection unit; and the projection unit for causing the luminous fluxes to carry image information and projecting these luminous fluxes onto a screen.
