HELP!- my screen is broken-imag0001.jpgHELP!- my screen is broken-imag0002.jpg

so my phone screen looks down..impact from the closing of a car door

i am trying to fix it myself. the outside screen (assuming gorilla glass) is fine. it's the inside that is messed up.
do i only need to buy a new lcd or do i need to buy more than that?
