It looks like there's a tiny piece of debris inside of the screen, most likely stuck between some of the backlight polarizers. The only way to fix this is to open up the screen and carefully clean the debris out, but this is a very sensitive operation that should only be done by a professional (even the tiniest scratch in a polarizer will show up permanently).
