Semiconductor device and display device

A display device comprising:

• a substrate having flexibility;
• a plurality of pixels provided on the substrate to form a display area;
• a transistor having a gate insulating film and further having a semiconductor layer and a gate electrode that sandwich the gate insulating film, is formed in an area where the substrate is bent;
• and
• a gate wiring line so formed on the substrate but in an area where the gate wiring line does not overlap with the semiconductor layer as to be connected to the gate electrode,
• wherein the gate electrode has an area that is present in an area where the gate electrode overlaps with the semiconductor layer and is thinner than at least part of the gate wiring line.

A display device comprising:

• a substrate having a bending part;
• a plurality of pixels provided on a display area, each of the plurality of pixels at the bending part including
• a transistor having a gate insulating film, a semiconductor layer and a gate electrode;
• and
• a gate wiring line being connected to the gate electrode,
• wherein
• the gate insulating film is between the semiconductor layer and the pixel electrode,
• the gate wiring line does not overlap with the semiconductor layer in plan view, the gate electrode has an area overlaps with the semiconductor layer in plan view, and the gate electrode is thinner than the gate wiring line.
