Title: DISPLAY DEVICE AND METHOD FOR INSPECTING DISPLAY DEVICE
Abstract:
This display device comprises: a plurality of signal lines which are arranged in a display region of a display panel; a plurality of transistors for inspection, which are electrically connected to the plurality of signal lines; an inspection wiring line which supplies an inspection signal to the plurality of transistors for inspection; and an abnormality determination unit which determines the presence or absence of an abnormality of the display panel. The signal lines are electrically connected to the gate electrodes of the transistors for inspection; the inspection wiring line is electrically connected to the drain electrodes of the transistors for inspection; and the abnormality determination unit determines the presence or absence of an abnormality of the display panel on the basis of the voltage level of the inspection signal at the source electrodes of the transistors for inspection.
