摘要：
A liquid crystal display (12) that minimizes disabling due to static electricity includes a rear polarizer and reflector (18), a front polarizer (30), and a display element (20,22) positioned between the rear polarizer and reflector (18) and the front polarizer (30). A transparent conductor (24) such as an indium tin oxide coating is deposited on the display element (20,22) between the display element and the front polarizer (30). The transparent conductor (24) is connected to electrical ground (26) to drain or dissipate any static electric charge applied to the display element (20,22). This dissipation of static electricity minimizes damage to the liquid crystal display (12) and disruption of the operation of the liquid crystal display (12).
