Abstract
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.
Claims12
A display device including a substrate on which a display region and a peripheral region having a scanning line drive circuit, wherein:
- the scanning line drive circuit includes a first wiring group having a clock wirings supplying clock and a first power wiring supplying power, a second wiring group having a second power wiring supplying power, and a plurality of unit circuits including five or more transistors;
- the unit circuits are located between the first wiring group and the second wiring group at the peripheral region in a plan view;
- the second wiring group locates between the unit circuits and the display region in the plan view;
- the first power wiring is the closest to the unit circuits among the first wiring group in the plan view;
- the second power wiring is the closet to the unit circuits among the second wiring group in the plan view;
- and
- the clock wirings disposed between the first power line and an end of the substrate in the plan view,
- wherein
- the unit circuits have a first unit circuit and a second unit circuit adjacent to the first unit circuit,
- the first unit circuit and the second unit circuit are connected via a coupling wiring,
- the coupling wiring locates between the first power wiring and the second power wiring in the plan view, and
- the first unit circuit and the second unit circuit are adjacent to each other in a second direction, and the second unit circuit is shifted from the first unit circuit in a first direction which crosses the second direction.
