Windshield is formed from "wind" (from Old English "wind", meaning air in motion) and "shield" (from Old English "scield", meaning a protective covering). The word "windshield" refers to a protective barrier against the wind, typically on a vehicle.
Think of a 'shield' that protects you from the 'wind' while driving — that's what a windshield does.
