摘要： A light source device includes at least two light emitting parts which emit light; and a polarization separating part which transmits polarized light in a first vibrating direction of the lights from the light emitting part, and reflects polarized light in a second vibrating direction nearly orthogonal to the first vibrating direction, thereby to separate the lights from the light emitting part into the polarized light in the first vibrating direction and the polarized light in the second vibrating direction. Herein, the light emitting part includes a reflection part which reflects light that travels toward the light emitting part from the polarization separating part, in the direction of the polarization separating part. The polarization separating part synthesizes the polarized light in the first vibrating direction that has passed through the polarization separating part, and the polarized light in the second vibrating direction that has reflected on the polarization separating part, thereby to cause the synthesized light to travel in a predetermined direction.

摘要： A display device includes a light source that supplies light, a phase modulator that modulates the phase of the light from the light source to form an image, and an imaging optical system that focuses the image formed through the modulation performed by the phase modulator. The phase modulator produces diffracted light according to a phase modulation pattern while changing the phase of the light so as to form an intermediate image between the phase modulator and the imaging optical system, and the phase modulator also changes the position of the intermediate image.

摘要： Aspects of the invention can provide an illuminator and others, which are able to supply polarized light having a certain oscillating direction as well as a certain wavelength range with high efficiency, and are suitable for a single-plate type projector using an LCD type spatial light modulator. The illuminator can include a light source, a rod integrator, a reflective polarizing plate, and a color filter. A reflecting mirror reflects polarized light, which has been reflected by the reflective polarizing plate, got injected into the rod integrator again through an emitting end, and progresses in the direction toward an injection end, in the direction toward the emitting end. Further, the reflecting mirror reflects light of any other wavelength range, which has been emitted through a first position of the emitting end, reflected by the color filter, got injected into the rod integrator again, and progresses in the direction toward an injection end, in the direction toward the emitting end to emit the light a second position that is different from the first position of the emitting end.
