It’s a messy job! Apple uses double stick foam to adhere the LCD panel to the cover glass.
So you need to be very careful taking the LCD panel off with all of the other components as any bending of the panel will damage it (micro fractures) and you need to clean the adhesive off without getting the viewable area sticky or wet as that will stain it.
I truely don’t recommend trying to do this if you haven’t done a few before as it’s also a bit of a skill.
While it’s is more costly, I would just replace the full assembly.
