What's the matter with my LED??? Is this a defect or not???

Question

While I watch a movie with my MBP 13", I noticed that there were some white band or stripe almost in the middle of my screen. At first, I think they were my fingerprint. I turned my computer off and cleaned LED screen. However, when I turned it on and opened black picture in full screen, they were still in the same place. When I looked at them closely, there are inside the screen!!!
In my town where I live (Columbia, MO), there are no apple retail store. Thus, it would be very helpful for me if someone could help me solve this problem or at least I wish I could know what the problem is.
Thank you in advance ^^

We've seen a few other reports here of pale marks on MBP displays similar to yours — in fact yours is only a partial version of some of the others. The full version is a rough circle 2" to 2.5" in diameter in the center of the display with a horizontal line passing across it from one side to the other, the line being near the top of the circle and spanning about half the width of the screen in all. What appears on your screen is part of the right side of the circle plus part of the right half of the line.
An explanation offered by Apple personnel to at least one of the previous posters was that the mark is caused by pressure on the back of the LCD panel — probably by the placing of excessive weight or pressure on the closed display during transport, as (for example) when carrying the MBP in a shoulder bag or backpack along with a load of books, and perhaps setting the bag down with the books on top of the MBP. Or having the MBP on the inside of a load in a backpack, with its display side pulled or pressed tightly against the wearer's back. Does it seem possible that your MBP might have been exposed to pressure in the center of its display back panel, where the Apple logo is? If so, then that may be the cause of your problem.
I would take it to an Apple Store Genius Bar for evaluation and see what they say about it.
Afterthought: I should add that I don't think there have been any reports here of such marks on a brand-new screen — all the machines in question had been used for some length of time before the marks were noticed.
