Abstract: A display device includes a substrate that includes a display area and a non-display area. A driver is disposed in the non-display area, and includes a driver circuit including a transistor and a driver control line transmitting a control signal to the driver circuit. A static electricity blocking line is disposed in the non-display area and circumscribes the display area. The static electricity blocking line at least partially overlaps the driver.
