My initial thought is display. Especially based on the bands of "normal" in between. These stripes almost certainly align with the cabling inside the display.
You can see what I mean a bit in this photo from a 13" model with the bottom bezel (where the MacBook Pro branding is) removed.
The best way to know for sure is to connect it to an external display. Normal video out is a dead ringer for it's a display issue.

Did you bang the hinge area or get something caught on the upper case when you closed the lid like a paperclip or other object near the hinge area?
Sadly, this is an expensive repair as the part alone is around $800
