Claim 15:
16. The image generation apparatus of claim 13, wherein the image generation apparatus comprises: an input polarizer for generating S- or P-polarized light; a reflective image display device comprising an alternate arrangement of at least one S and P-modulating reflective display region that is selectively controllable for generating correspondingly reflected S/P polarized image bearing light; an S- or P-output polarizer for generating filtered S- or P-polarized image bearing light; and at least one first P-polarization blocking filter which is arranged to block, in an S-polarized image bearing return path, the propagation of P-polarized light towards the output surface, and/or an S-polarization blocking filter which is arranged to block, in an P-polarized image bearing return path, the propagation of S-polarized light towards the output surface.
