My kid dropped my first generation iPhone and now several parts of the display only show grey. Looks like some pixels died. There are no cracks on the screen and touch works in the areas that are grey.
What should I replace to fix this? I believe the screen is made up of different components (glass, LCD etc). Should I replace the whole display unit or can I just replace the part that is broken?

It's unlikely that the pixels have died, but the edge connector of the screen may have become dislodged or damaged, or it could be that the connection to the logic board could be loose.
You can try following this ifixit guide to see if taking it apart and reassembling it will restore any bad connections that dropping it may have caused.
If that doesn't work, you can just replace the display, as on pre iPhone 4 models the screen/digitiser and display are separate components, so if that's the only damaged component then it should fix the problem.
