1. A display device comprising: a display unit in which scanning lines of a plurality of types are disposed as horizontal scanning lines; and a plurality of scanning drive circuits configured to drive the scanning lines of the respective plurality of types, the display unit having a non-rectangular shape, wherein
a region inside the display unit is segmented into a high-load region with a high load on the horizontal scanning lines and a low-load region with a low load on the horizontal scanning lines,
scanning lines of the plurality of types disposed in the high-load region are driven by the respective plurality of scanning drive circuits,
scanning lines of the plurality of types disposed in the low-load region are driven by one of the plurality of scanning drive circuits,
each of the plurality of scanning drive circuits includes a shift register,
the scanning lines of the plurality of types includes first type scanning lines and second type scanning lines, and
the plurality of scanning drive circuits includes a first scanning drive circuit configured to drive the first type scanning lines disposed in the high-load region, the first type scanning lines disposed in the low-load region, and the second type scanning lines disposed in the low-load region, and a second scanning drive circuit configured to drive the second type scanning lines disposed in the high-load region.
