Abstract:
A projective image display apparatus that modulates light with a display panel and projects modulated light with a projecting lens to display an image, the apparatus comprising:a first light source to emit a light beam;a second light source to emit a light beam;an integrator optical system, having a first lens array and a second lens array, to effect, through use of the first lens array, an imaging of light beams emitted from the first light source and the second light source on the second lens array, and to effect an illumination of an entire surface of the display panel, wherein the first lens array receives light beams emitted from the first light source and the second light source; anda polarization conversion optical system, positioned subsequent to the first lens array, to separate received light beams, which passed through the first lens array, based on an oscillation direction of the light beams and to convert a first oscillation direction of at least a portion of the received light beams to a second oscillation direction.
