Typical chicken/egg problem. They're over 10k because of low production runs and they're targeted towards industries that spend big, like the medical industry. If they were sold to the mass market then they would be close in price to your typical 32" LCD TV. Why are 16:9 ~21" 1080p screens so cheap, because they're parts from small LCD TVs! It's really the lack of demand that causes it. The sony LCD projector screen I quoted for example (it didn't have a backlight, it was just the lcd), you could purchase for around or under a $100.
