After drop, screen has transparent grey bar, can I fix?

I dropped my mackbook air after which the screen displays a vertical transparent grey bar across most of the screen width and some flickering lines at the top and bottom. I can still see enough to use it but the grey bar etc.is inhibiting.

When the background is white there is no apparent interference although the colours are a bit washed out under the grey bar. The problem is awful when the background colour is grey with many flickering horizontal lines.

I have checked the connector to the screen and it appears to be locked correctly.

Do I need to replace the display?
