Rex,
This is a very good question! I am not very knowledgeable on this subject but this is what I could find.....
LCD Motion blur is largely caused by the hold-type rendering method of LCDs together with the motion pursuing function of human visual system. This hold-type motion blur happens not on the LCD screens but in human eyes, so it cannot be captured by a still camera and therefore is physiological. Even if response time is reduced to zero, motion-blur will be observed.
So it appears, LCDs don't suffer from motion blur but the brain does.

Here are the names of 2 papers that provided this information:
LCD MOTION BLUR MODELING AND ANALYSIS - Sharp Labs of America
Nonlinearity compensated smooth frame insertion for motion-blur reduction in LCD - Samsung Electronics Co
