It's likely the digitiser (Touch Screen portion of the screen) is damaged and needs replaced. To be honest as this is quite an inexpensive phone it's probably a better option to sell it for spares and buy a replacement. A replacement digitiser and the time to repair wouldn't really be worth it. But if you do want to repair it you would need to pick up a new LCD + Digitizer. They generally come as one piece. It's possible to buy the digitizer seperately but it requires specialist equipment to remove the old one from the screen you have and is a complicated repair.
