3-D image display device
First Claim
1. A 3-D (dimension) image display device comprising:
- a display element to emit light according to image information for a left eye and image information for a right eye;
an image separation unit to separate the emitted light into a left image and a right image corresponding to the image information for the left eye and the image information for the right eye;
a polarization conversion switch to sequentially switch a polarization direction of the light; and
a birefringence element to transmit or to refract the light, depending on the polarization direction of the light that has passed through the polarization conversion switch, shifting the light whose polarization direction has been switched by the polarization conversion switch.

Abstract
An image display device to display both a 2-D image and a 3-D image. The image display device includes a display element, an image separation unit, a polarization conversion switch, and a birefringence element. The display element emits light according to image information for a left eye and image information for a right eye. The image separation unit separates the emitted light into an image for the left eye and an image for the right eye. The polarization conversion switch sequentially switches the polarization direction of the incident light. The birefringence element transmits or refracts the light, depending on the polarization direction of the light that has passed through the polarization conversion switch. An image, whose polarization direction has been switched by the polarization conversion switch, is shifted when passing through the birefringence element, whereby the left eye image and the right eye image resolution is improved. The polarization direction of incident light is sequentially switched by the polarization conversion switch, and the image, whose polarization direction is switched, is shifted by the birefringence element, so that the resolution of a 3-D image is improved.
