Fry's Outpost (outpost.com) has an Axion AXN-6070 portable DVD player on sale for $130 US. This includes a 7" TFT LCD, but all they say is "high resolution" instead of any number of pixels. It includes A/V input, so you could also connect it to a cable or satellite box, or a VCR.
I have not seen it in person, and I have no idea if it can be stripped for projection. But that is a pretty good price for a portable DVD player AND a 7" LCD. Even if it is all glued together, you could still use it in your car: It includes a car adapter.
