A display device includes scanning lines disposed along rows of display pixels, signal lines disposed along columns of the display pixels, pixel switches disposed near intersections between the scanning lines and the signal lines, pixel electrodes connected to the pixel switches, a counter-electrode disposed to be opposed to the pixel electrodes, storage capacitance lines disposed substantially parallel to the scanning lines, first inspection switches connected to the scanning lines in a peripheral section, second inspection switches connected to the signal lines in the peripheral section, a first wiring line which supplies a signal for turning on/off the first inspection switches, a second wiring line which supplies a signal for turning on/off the second inspection switches, and a third wiring line which applies a signal to the counter-electrode and the storage capacitance lines.
