You will need to get the whole screen replaced more than likely. however sometime though very rarely the ribbon cable for the screen shifts off the board and you get this type of issue. either way you need to open u the phone and look and try reseating the ribbon cable. if that doesn’t work you just need a new screen and honestly the disassembly is the hardest part.
you will also need to get some double sided tape I like to use the non conductive type and you can get a set of 4 rolls of various widths from amazon.

It appears that you have a dead screen. Have you dropped your phone without a case before this happened?

Ah, well, You probably just need a new screen. You can find parts on iFixit and amazon.
