Claim 12:
13. A method for driving a display device including a display unit in which scanning lines of a plurality of types are disposed as horizontal scanning lines, the display unit having a non-rectangular shape, the method comprising:
a low-load region driving step of driving, by one of a plurality of scanning drive circuits, scanning lines of the plurality of types disposed in a low-load region with a low load on the horizontal scanning lines, the low-load region being a part of a region inside the display unit; and
a high-load region driving step of driving, by the plurality of scanning drive circuits, scanning lines of the plurality of types disposed in a high-load region with a high load on the horizontal scanning lines, the high-load region being a part of the region inside the display unit, wherein
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,
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, and a second scanning, drive circuit configured to drive the second type scanning lines disposed in the high-load region,
in the low-load region driving step, the first type scanning lines disposed in the low-load region and the second type scanning lines disposed in the low-load region are driven by the first scanning drive circuit, and
in the high-load region driving step, the first type scanning lines disposed in the high-load region are driven by the first scanning drive circuit and the second type scanning lines disposed in the high-load region are driven by the second scanning drive circuit.
