  • Publication number: 20090109154
    Abstract: Disclosed is a display device adapted to selectively display a normal image, a stereoscopic image, a multi-view image and a stereoscopic multi-view image is disclosed. The display device includes a liquid crystal panel displaying an image; a polarizer disposed on the liquid crystal panel; a liquid crystal lens disposed on the polarizer; and a polarizing member interposed between the liquid crystal lens and the liquid crystal panel, wherein an axis of light transmitted through the liquid crystal lens coincides with an optical axis of the polarizer. Accordingly, the display device can selectively display a normal image, a stereoscopic image, a multi-view image and a stereoscopic multi-view image, while improving the picture quality and the brightness.
