It's a zebra strip. There are lots of tiny conductors running between
the PCB and the LCD that are all insulated from one another. If you
imagine these it looks like a Zebra, hence the name.

The plastic piece clamps the LCD glass to the circuit board putting
the "correct" amount of compression on the zebra strip so it's
connected in the circuit. In production the screws would be put in
with a torque screwdriver so the strips are compressed the prescribed
amount.
