A display device includes a substrate having a display area and a non-display area. A plurality of pixel electrodes are arrayed in a matrix within the display area on the substrate. A plurality of display elements are arranged corresponding in position to the pixel electrodes. A plurality of switching thin-film transistors are connected respectively to the pixel electrodes. A plurality of scanning lines are provided to supply a scanning signal to the switching thin-film transistors. A plurality of data lines are provided to supply a data signal to the switching thin-film transistors. The non-display area of the substrate includes a driver forming area in which a driver for driving at least one of the scanning line and the data line is to be mounted, and a static-electricity protecting circuit is provided in the driver forming area.
