That does not look good at all. You can try the following troubleshooting tasks and see whether that resolves the issue. I strongly feel that this one is a hardware issue.

  1. Reset SMC by following the directions applicable to your MacBook here ➔ How to Reset SMC. If that does not solve things then-
  2. Reset NVRAM/PRAM by following the directions applicable to your MacBook here ➔ How to Reset NVRAM/PRAM. If that does not solve things then-
  3. Enter ➔ Safe Mode and see if the screen issue still exists in Safe mode. Log out of Safe Mode and then reboot computer. If that does not solve things then-
  4. This is probably a hardware issue and related to the Display or the connecting Cable or the Logic Board. I recommend that you have your MacBook Air examined at the Apple Store or at an Authorized Service Center.
