Could LCD fluid be leaking into white casing?

I only just got a white macbook (late) for christmas, and it had been great until a few days ago. on the back of the screen (the side where the apple logo is) there are these weird grey blobs. i have not spilt anything on it. this is nothing that a magic eraser will get rid of. i have scratched it to try and get it off, and where the scratches are, it is as if the blob is underneath the plastic, and it is not risen. so my guess is that the Liquid crystal display, has somehow leaked out through the casing. is this possible? since it is faulty, and not my own fault, will apple repair it under my warranty, and if so, how long will it take to get repaired. (oh and two more are starting to appear, but they are more pale in color). thanks, any answers are greatly appreciated. x
