1. A display device comprising:
a plurality of pixel electrodes;
a plurality of pixel circuits below the plurality of pixel electrodes;
some scan lines, each of the scan lines being connected to a corresponding one group of the plurality of pixel circuits; and
a scan drive circuit configured to selectively send scanning signals to the scan lines,
wherein
the plurality of pixel electrodes include effective pixel electrodes corresponding to respective pixels constituting a displayed image, and dummy pixel electrodes between the effective pixel electrodes and the scan drive circuit and corresponding to none of the respective pixels,
each of the effective pixel electrodes is connected to a corresponding one of the plurality of pixel circuits,
each of the scan lines is electrically connected to the scan drive circuit through a corresponding at least one of the dummy pixel electrode, and
each of the plurality of pixel circuits includes a thin film transistor with a gate electrode, the gate electrode being connected to a corresponding one of the scan lines.
