Why does it have to be an LCD? Why not something simpler? In order to read the resistance you need two wires, if you only have 5 wires...!??? Why not just buy a 100 $5 ohmmeters? Why not look for schematics on line? You might want to buy a simply ohmmeter, rip it apart, throw it a way, buy a new one, carfully take it apart, and map the circut. You will have just created a schematic of an ohmeter. You will then know all of the componets and values needed to build your own. Your best bet would to buy a bunch of cheap basic ohmmeters. It will be cheaper in the long run...
