It's the pressure marks, something is pressing on the back panel of the LCD screen causing this kind of bright areas. It's not dead pixels.
I have some small areas like this on my brand new Razer Blade 14, this is a very common flaw in LCD manufacturing process and it is not something you can fix by yourself. You've got 2 choices: return the product until you get a perfect one, or, live with it.
