Display device

A flat panel display is disclosed. The flat panel display includes a display panel having a display area on which a plurality of pixels are formed, an inspection pad formed in a non-display area outside the display area of the display panel, an inspection switch formed in the non-display area, and an electrostatic protection circuit including a plurality of dummy thin film transistors (TFTs) whose gate electrodes are commonly connected to a signal line connecting the inspection pad to the inspection switch. The inspection pad contacts an external inspection device. The inspection switch applies an inspection signal received from the inspection pad to the pixels.
