There's no way for me to say for sure, but I suspect that some of the light leaking from below is reflecting around in front of the lcd layers (but below the surface glass). The glass (or plastic) at the front has a refractive index (RI). Light that hits it at a certain angle (depending on the RI) is going to reflect rather than going through. Thus, if you have light leakage from below, some of that light is going to be reflected off the front surface of the screen back towards the LCD and then reflected again back out resulting in patchy spots of light elsewhere. Patchy probably because the screen surface on the LCD is not PERFECTLY flush. Which it wouldn't need to be if there wasn't light leaking from below.
The fact that you see them when you're watching movies or have images up, only reinforce my belief that the light leakage is from the front of the screen, rather than from behind (which would suggest an actual LCD manufacturing defect).
Plus, I suspect the spots are somewhat accentuated in your pics, since you can see that the Windows logo is flared.
