Patent ID: 8427529

Claim:
A three-dimensional display, adapted for a viewer to watch through glasses with two lenses having polarized directions perpendicular to each other, the three-dimensional display comprising: a display panel comprising a plurality of pixels arranged in array and a polarizer, wherein the polarizer being disposed between the pixels and the glasses and having a transmission axis, and the display panel is suitable for displaying an image; and a liquid crystal phase modulator disposed between the display panel and the glasses and comprising a liquid crystal layer and an alignment layer adjacent to the display panel, wherein an included angle between an alignment direction of the alignment layer and the transmission axis is substantially equal to n×45 degrees, an absolute value of n being an integer, the liquid crystal phase modulator is suitable for providing a phase retardation, the liquid crystal phase modulator adjusting a phase of the image to output an image with three-dimensional information, and the liquid crystal phase modulator comprising no polarizer.
