Abstract: It is possible to reduce a size of a lower frame region to ensure a wiring corrosion margin equivalent to that of a conventional technique. In a display device, a video signal wiring arranged in the lower frame region includes, in a region between a terminal section (terminal) and a video signal line, a first wiring formed on a first wiring layer and having one end connected to the terminal section to which a video signal line driving circuit is connected, a second wiring formed on a second wiring layer different from the first wiring layer and having one end connected to the other end of the first wiring, and a third wiring formed on the first wiring layer and having one end connected to the other end of the second wiring. The other end of the third wiring is connected to the video signal line via a fourth wiring formed on the second wiring layer, and the first wiring layer is formed on the side closer to an array substrate than to the second wiring layer.

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.

Abstract: Even when a light shielding film is provided between a transistor and a substrate, a threshold voltage of the transistor can be prevented or suppressed from being shifted. A display device includes light shielding films provided between a substrate and a semiconductor layer of a transistor including a gate electrode and the semiconductor layer. The semiconductor layer includes a source region and a drain region. Both of the light shielding films overlap the semiconductor layer when seen in a plan view, and are spaced apart from each other in a direction.

Abstract: The presence or absence of touch is detected according to a difference of a capacitance caused by the presence or absence of a material that blocks the electric field formed between the detection electrode and the common electrode. The common electrode includes a plurality of divided electrode portions that is extended in a lateral direction and aligned with each other in a longitudinal direction. Each of the plurality of common lines is electrically connected to at least one of the divided electrode portions. The plurality of common lines is arranged in an area next to the common electrode in the lateral direction of the common electrode, arranged next to each other in a width direction orthogonal to a length thereof, is different in width from each other, and the width of the common lines is wider as the length is longer.
