Panasonic 103-inch HD Plasma Display
Panasonic's TH-103PF9UK ($70,000) is the world's largest high definition plasma display. As if you needed to read further after that fact, the super-sized display offers 103-inches of screen space (equivalent in size to four 50-inch Panasonic plasma displays) and is native 1080p with a full HD pixel resolution of 1,920 horizontal x 1,080 vertical. It may be designed for corporate use, but that won't stop you from hanging one in the den (and probably then losing your wife). Note though that it requires professional installation due to its weight and size.
