Abstract: A display device includes a display panel, a first inspection line, a second inspection line, and an inspection circuit controlling a connection between the first inspection line and a first pixel group and a connection between the second inspection line and the second pixel group. The inspection circuit includes a switching part including a first switching part that controls the connection between the first inspection line and the first pixel group and a second switching part that controls the connection between the second inspection line and the second pixel group and a dummy circuit including a dummy transistor that is electrically connected to the switching part and including a first dummy electrode, a second dummy electrode that is connected to the first dummy electrode, and a dummy control electrode.
