Claim 11:
12. 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 scanning drive circuits includes a shift register,
a shift register included in a scanning drive circuit that is configured to drive scanning lines disposed in the low-load region includes, excluding a unit circuit that does not contribute to display, unit circuits corresponding to scanning lines disposed in the low-load region and unit circuits corresponding to scanning lines disposed in the high-load region,
a shift register included in a scanning drive circuit that is configured to drive only scanning lines disposed in the high-load region includes, excluding a unit circuit that does not contribute to display, only unit circuits corresponding to scanning lines disposed in the high-load region,
an output signal from each unit circuit included in the shift register is provided to a corresponding scanning line and a unit circuit of a subsequent stage, and
regarding a shift register included in a scanning drive circuit configured to drive scanning lines disposed in the low-load region,
each unit circuit corresponding to a scanning line disposed in the high-load region is provided with an output terminal configured to output the output signal to a corresponding scanning line; and an output terminal configured to output the output signal to a unit circuit of a subsequent stage, and
each unit circuit corresponding to a scanning line disposed in the low-load region is provided with only one output terminal configured to output the output signal to a corresponding scanning line and a unit circuit of a subsequent stage.
