Your photo illustrates LCD damage - and what appears to be a visible crack above the camera island at top dead-centre of the screen. The only remedy for a damaged screen is replacement.

The screen is the single most expensive component of your iPhone. Assuming that you are resident within a country that has official Apple support representation, Apple offers a fixed-price price repair. You can verify eligibility and cost for your region/country here:

iPad Repair & Service - Apple Support

If you have an active AppleCare+ plan, the cost of repair is reduced to a small excess/deductible fee.

Good eye. I didn't notice the crack in the screen in the photo. You are most likely correct that the phone screen is damaged and needs to be replaced.
