With 99,9% certainty that's the LCD.
You can try and remove the LCD-bezel, then put some pressure on the (left) side of the screen where that bad band begins.
If that improves, put a piece of carton or something there and put the LCD-bezel back to keep that in place.

This is only a temporary fix (if it works at all) for a few days or weeks at the most.
Start looking for a new screen. See also this: viewtopic.php?f=45&t=116198

Use an external screen if needed.
But if an external screen shows the same, you'll need a new motherboard.

Yeah It's display. I connected the display to another laptop and the problem is the same. I will simply buy a new display.
