Abstract
According to one embodiment, a display device includes an optical modulation element configured to emit image light corresponding to an image by using illumination light from an illumination device, a polarization control element configured to emit first polarized light, and second polarized light on the basis of the image light receiving from the optical modulation element, a polarization separation element configured to transmit the first polarized light as transmitted light and reflect the second polarized light as reflected light, and a projector configured to project the transmitted light onto a first projection area of a projection plane, and projects reflected light onto a second projection area of the projection plane.
Claims20
A display device comprising:
- an illumination device configured to emit first light;
- an optical modulation element illuminated by the first light and configured to emit second light;
- a polarization control element configured to receive the second light and to emit first polarized light and second polarized light different from the first polarized light;
- a polarization separation element configured to receive the first polarized light and the second polarized light, to transmit the first polarized light as transmitted light, and to reflect the second polarized light as reflected light;
- at least one retardation plate configured to transmit at least one of the first polarized light or the second polarized light;
- a projector configured to receive the transmitted light and the reflected light from the polarization separation element or the at least one retardation plate;
- and
- a projection plane having a first projection area and a second projection area different from the first projection area, and configured to receive the transmitted light and the reflected light from the projector,
- wherein the projector is configured to project the transmitted light onto the first projection area and to project the reflected light onto the second projection area.
