Display device
A display device with a variant-shape display region other than the rectangular display region is configured to form a scanning line drive circuit along the variant-shape display region. The scanning line drive circuit includes bus wiring group with clock wiring for supplying clocks with three or more phases and the power supply wiring for supplying power, and the unit circuits for configuring the shift register including five or more transistors. The bus wiring and the unit circuits are formed on the different regions so as not to cross with one another.
